1. Improve Prison Conditions

Though problems like poverty and underdevelopment are often considered to be the root causes of crime, the formation of gangs after criminals have been arrested can be curbed with the improvement of living conditions inside detention facilities.  Currently, prisoners justify their rioting, brutality against guards, and general violence as retaliation against, and protection from, states that violate their basic rights.  Whether from a lack of prisons or stringent arrest policies, overcrowding plagues the prison systems of the United States, Mexico, and Central and South America.  Prisoners from the latter three regions complain they are denied basic necessities like blankets and soap, and international human rights organizations validate their claims.  If authorities address inadequate living conditions, prison gangs will be denied the foundations of their moral claims, and possibly, the subsequent support from sympathetic and often impoverished populations outside the prisons (i.e. in Central and South America).

2. Inmate Labor for Underdeveloped Neighborhoods

If infrastructure deficiencies and underdevelopment are contributing to poverty-based crime in place like Central and South America, then development projects aimed specifically at these higher-risk neighborhoods may help prevent young people from joining gangs out of economic desperation.  Additional manual labor programs for prisoners would reduce the costs of development and contribute to long-term solutions to the gang problem.  By partnering with non-government, non-profit, or charitable development organizations, law enforcement officials could bring economic stability to the impoverished populations that contribute to and often support the illegal operations of gang members.  Using inmate labor would also remove prisoners from the overcrowded conditions of their cells.

Risks, of course, exist.  The chances of prisoner escape during projects increase, so programs would have to be accompanied by an increase in the number of prison guards.  Communication between prisoners and non-inmate gang members may also be facilitated by the travel.  Cell phones inside prisons, however, already allow inmates to communicate with their colleagues; adding “community service” to prisoners’ daily activities may serve more as a distraction than as an added benefit for them.

3. Separate Housing Facilities Based on the Nature of the Crime

Prisoners should be housed in separate facilities based on the crime committed.  For example, inmates convicted of less serious crimes (i.e. vandalism and petty theft) would be placed in one detention block, while those guilty of serious crimes (i.e. murder and drug trafficking) would be placed in separate blocks.  This policy goes beyond isolating gang leaders and members from the general prison population, although the intended aims are the same: the prevention of gang “contamination” of unaffiliated prisoners.  The majority of individuals are incarcerated for a variety of petty crimes and often have little interest in gang culture.  But when these inmates are mixed with prisoners from other criminal professions, there is a high probability they will encounter individuals who proselytize the economic and personal merits of gang membership.  By recruiting inmates with diverse backgrounds, prison gangs gain new contacts to diversify their criminal networks (acquiring the skills of counterfeiters, marijuana growers, etc.), making them harder to disrupt and dismantle.  By isolating gang members from regular prison populations, and further separating prisoners according to the nature of the crime committed, the pool of criminal knowledge available to the prison gangs will be restricted and gang membership will decrease.

4. Increase Funding for Prison Guards

Most prison officers in the United States and Latin America are paid wages lower than other professions, tempting them facilitate the activities of prison gangs to supplement their incomes.  An increase in funding for prison personnel will not only provide higher salaries to stave off corruption, but also lead to more guards per prisoner strengthening state authority and the ability monitor illicit gang activity.  However, the opportunity costs may include less funding for food, training, and rehabilitation programs, etc.  In times of economic stress, intelligent retrenchment strategies (i.e. targeted cuts) from the various prison systems in the United States and Latin America can locate funding for guards to offset the opportunity costs in a satisfactory manner.

5. Build More Supermax Prison Facilities

To successfully alter the effectiveness of prison gangs, there is a strong need to build more exclusive maximum security prison facilities.  There are numerous maximum security prisons throughout the United States and other nations, but the majority rely only on a designated area in which the most dangerous inmates are housed.  The ADX supermax prison facility in Florence, Colorado, is entirely designated for the most dangerous offenders and has largely been a success story in keeping these offenders in complete isolation, essentially cutting off their influence in the outside world.  Gang leaders thrive off the ability to reach prison populations with their ideology and recruit more members.  Therefore, there is a need to keep leaders in total isolation in these maximum security prisons where such communication is an impossibility.  Supermax facilities like the one in Florence, Colorado should be replicated throughout the United States and Latin America to meet the challenges of housing prison gang leaders separately from their soldiers.  This approach is very costly, yet it is the most effective strategy for crippling the capabilities of prison gangs by diminishing the influence of the men who dominate the decision-making of gangs.

6. Gang Prevention Programs

Increased opportunities for education and gang prevention are two policy options that may further decrease gang activity.  The U.S. Department of Justice, Office of Juvenile Justice, and Delinquency Prevention recommends a number of prevention strategies such as parent training, after school activities, truancy and dropout prevention, re-entry programs, tracking former offenders, and job programs for youth in high-risk neighborhoods.  The Gang Resistance Education and Training (GREAT) program places uniformed police officers as instructors in middle schools to teach students about the negative consequences of gang participation.  Non-profit groups like the Boys and Girls Club of America provide after-school activities that may keep children from joining gangs.  Some Central American countries have also enacted programs designed to prevent youths from turning to gangs, such as the Open Schools program to keep schools in high-risk neighborhoods, or “red zones,” open on the weekends and various vocational training efforts.  In Guatemala, for example, an alliance of human rights organizations provides schooling and social development activities to help at-risk youths raise their self-esteem.  These programs form an important starting point for Central America, Mexico and Brazil, but they should be expanded further, drawing on successful U.S. programs.  A scaled-up effort to change youth attitudes toward gang involvement could drastically reduce gang membership in the long run.

7. International Action to Address the Root Causes of Poverty and Interrupt the Drug Trade

National legislation is an important step in combating the prison gang problem.  However, most Central American countries lack strong government structures, resources, and incentives to enforce national laws.  International efforts are needed to strengthen the rule of law, address poverty, and expand educational opportunities.  National governments must continue their efforts to strengthen internal governance, increase stability, and create fair legal procedures, but Central American nations have thus far been unsuccessful at solving the problems posed by gangs alone. The only way to address these problems is with assistance from other countries in the form of an international initiative to address the root causes of gang activity.

8. Inmate Therapy

Rehabilitative programs offer another way to combat the root causes of gang membership.  Expanded rehabilitation efforts would serve to reintegrate gang members back into society.  As Juan Fogelbach has argued, “Gang members should be provided with alternatives to gang life, including education, music, art, youth sports, and trades that may allow them to survive in society.”[1]  Rehabilitation programs that assist gang members in developing a sense of self-esteem and acquiring skills to gain legal income will further deter gang activities.

Key Findings

Similarities between Prison Gangs in the United States and Latin America

1. Reasons for Expansion

Prison gangs from all four regions under examination were created as a form of self-protection, either from other inmate groups or from poor conditions and abuse by guards.  Once established, their reasons for expanding inside detention centers continued to focus on defensive measures; even offensive attacks against other inmates or guards are justified as defending the gang’s control over territory, people, or illegal commodities trades.  Recruiting other inmates strengthens the group physically, psychologically, and sometimes monetarily.

Once prison gangs establish operations outside prison walls, however, the profit motive becomes more important for expansion than self-protection.  Gangs may use their profits to increase prison activities, but greed often overshadows such intentions.  The gangs grow more violent as they evolve into arms and drug trafficking organizations because: (1) brutal reputations reinforce gang power on the “outside” (as opposed to reputations as protectors on the “inside”); (2) competition from other, often transnational, trafficking organizations increases; and (3) the expansion of power inside or outside detention facilities sparks rival factions and gang warfare that spreads from the prison system to the outside or vice versa.

States authorities must comprehend the differing reasons for gang expansion inside and outside prison if they are to effectively combat these growing prison organizations. Different anti-gang programs may be needed to address inmate and non-inmate gang members.

2. Gang Cooperation as a Response to State Activity

Prison gangs in the United States and Latin America have proven themselves to be remarkably adaptive to state actions against them.  In Rio de Janeiro, for example, prison-based gangs have battled each other for control of the city’s favelas for decades; yet, in response to Rio’s pre-Olympics/World Cup crackdown on drug dealers, several of the groups—such as Comando Vermelho and Amigos dos Amigos—have called truces in order to battle their common enemy together.

In the short-term, if the state attempts to eradicate one gang at a time, it may be more likely to achieve its goals than if it attacks all at once.  Gangs are less likely to interfere with state actions if they are seen as eliminating rivals.  In the long-term, however, a one-at-a-time approach may serve to strengthen the prison gangs that are addressed last by eliminating their competition, making complete eradication more difficult.  At the very least, gang cooperation in the face of state oppression provides law enforcement with a single enemy on which to concentrate its resources.

3. Prisons as Bases Strengthen Trafficking Organizations on the “Outside”

In the 2010 Small Arms Survey, Benjamin Lessing notes that the strongest law enforcement initiatives give prison gangs greater control over their non-inmate members.  While this seems counter-intuitive, gangs in the United States and Latin America prove the point.  Law enforcement officials in the United States, Mexico, Central America, and Brazil have the legislative authority and practical capability to arrest gang members for a variety of offences. Yet, the higher likelihood of a prison sentence means that gang members increasingly expect to face their leaders in jail, and thus to receive punishment for disobedience while they were on the streets.

This finding suggests the importance of interrupting communications between inmates and non-imprisoned gang members.  Often, a gang’s most powerful leaders are imprisoned but not sufficiently isolated, undermining the effect of efficient policing.

4. Recruitment via the Prison Establishment

Most law enforcement officials recognize the role of prisons as breeding grounds for gang membership.  Non-affiliated prisoners often join gangs after being arrested as a form of protection from other inmates.  In such cases, the reason prison gangs often form in the first place (self-defense) is the same incentive that new inmates have to lessen the threats that those gangs present.  The cyclical nature of recruitment implies the need for stricter separation of the inmate population or better prevention of inmate-on-inmate violence.

5. Decentralization

While all of the observed prison gangs have a centralized command structure within their own organization, the criminal networks in which they operate are more decentralized in nature.  These decentralized networks include smaller street gangs, drug traffickers, other prison gangs, and any other unlawful group that wishes to cooperate with the prison gangs for monetary benefit.  An advantage of these types of networks is that the disparate groups which comprise them draw less scrutiny from law enforcement, enabling the wider illicit activities of the prison gang in command to go unnoticed and unabated.  Should law enforcement officials decide to crack down on one part of the network, the greater whole will survive to continue to funnel money and weapons to the gang in charge.

6. Communication with External Supporters

The purpose of prison systems is to lock away criminals as punishment for their misdeeds against society, yet all of the observed prison gangs have the ability to communicate with members on the “outside.”  Communication is often enabled through family and friends who carry messages out of the corrections facilities after a scheduled visit.  When personal connections on the outside are unavailable, bribing or coercing prison guards to act as intermediaries often suffices.  Prisoners have a tendency to acquire female supporters through written letters and, in the case of the U.S.’s TRULINCS program, email correspondence to invoke sympathy for their plight.  These sympathizers are then willing to smuggle contraband into prisons, including mobile communication devices hidden in the soles of their shoes.  Usually, women act in support roles for prison gangs, with the exception of the Nazi Low Riders.  Wives and girlfriends of incarcerated NLR members actually run the gang’s drug business on the outside and sometimes commit violent crimes on their behalf.

7. Involvement in the Drug Trade

Prison gangs, much like street gangs, are heavily involved in drug trafficking as a primary source of income.  All of the observed prison gangs engage in some aspect of the drug trade including trafficking, wholesale supply, or retail sale.  In all cases, gangs had to dramatically increase membership to meet the demands of drug trafficking operations, the majority of which are transnational in nature.  The common drugs involved in all four regions are marijuana, heroin, and cocaine.  Involvement in the drug trade has proved to be very lucrative for all prison gangs, bringing in large sums of cash that are used to purchase firearms, strengthen membership, and fund more operations.

8. Brutality

Common among all prison gangs is the use of brutality as a premier tool with which to accomplish ends.  All of these prison gangs have distinguished reputations for violence and ruthlessness, both inside prison and outside in the streets, and all are feared among other inmates.  Prison gangs only accept the most violent inmates into their respective ranks because intimidation in prison is the primary goal of any gang and the only way to ensure survival.  In all cases, these prison gangs utilize the murder of other inmates and gang members to earn respect and build an image that instills fear in possible enemies.  Across all four regions, prison gangs display brutality that attracts a great amount of attention from law enforcement, who often develop a strong fear of prison gangs.

9. Dispersion of Members by Authorities

In all of the cases we have studied, authorities have attempted to break up prison gangs by dispersing key members to separate facilities.  This approach, however, has not had the intended effect of crippling prison gangs and has, on the contrary, proved counterproductive in all four regions.  As leaders are separated from their gangs, they are moved to other facilities providing new opportunities to spread their gang’s ideology to a new population and recruit even more members.  As a result, prison gangs have rapidly expanded into new territories, opening up new chapters and creating even more widespread instability for the state.  In most cases, dispersion of gang members, including deportation, has transformed gangs like MS-13 and other Latino prison gangs from national to transnational threats.

10. Lack of Rehabilitation Programs Inside Prisons

All of the prison gangs in the United States and Latin America lacked rehabilitation programs aimed at combating the root causes of gang membership and changing gang behavior.  This is partly caused by the insecure prison environment that creates the need for protection within prison walls and the corruption of prison officials who may benefit from the gangs’ illegal activities.  In U. S. prisons, rehabilitation programs include substance abuse and mental health programs, educational programs, and vocational training.  In South America, there are no prison rehabilitation programs and many inmates reported lack of work or other constructive activities in prison.  In Mexico and Central America, prisons lack rehabilitation programs but do provide some religious programs for gang members.

11. Release from Prison Back into Previous Environments

In all the countries we have studied, the location of prisoners after they are released is an area that all the prisons systems have neglected.  In fact, all of the countries’ prison systems lack an effective mechanism that could potentially remove gang member from their previous environment. The lack of such a capability is problematic because these environments may foster the previous gang life style and lead the gang member back to prison.

12. Unemployment Serving as a Mechanism Pushing Gang Members Back into Previous Gang Behavior

Unemployment among recently released inmates is widespread throughout all the countries we studied.  Gang members leave prison without any resources and return to criminal activity as a means of income.  Many gang members in these countries make connections in prison that allow them to acquire new criminal knowledge and venture into new criminal enterprises.  In the United States, there are outside organizations that will help the prisoners find employment.  These programs may provide some incentive for the gang members to cease their gang activity; however, program success has been limited since the income provided from employment is substantially less than the income gained from criminal activity.

13. Gang Codes Keep Inmates Involved in Gangs Outside the Prison System

All of the prison gangs in the United States and Latin America operate under codes which outline rules gang members must follow under threat of punishment.  In the prison system, the protection and benefits that flow from the gang relationship provide incentives for gang members to follow these rules.  Gang codes also effectively keep gang members loyal to prison gangs after they are released, since the high rate of recidivism creates the possibility that members will end up back in prison system.


1. National Approaches to Reform

Despite the similar patterns witnessed in the operations of U.S. and Latin American prison gangs, states have taken drastically different approaches in attempting to solve their inmate-related problems.  In the United States and Brazil, officials have discussed reducing prison sentences.  In Central America, a potential law enforcement reform includes the reduction of “hard hand” arrests, whereby people are arrested because of their gang tattoos, without having committed a crime.  Brazil has also considered adding more education programs for inmates.

On the one hand, the different tactics supply law enforcement communities with a wider pool of experiments from which to learn.  Different countries often require culture- and environment-sensitive reform programs to address the specific problems relevant to their prison systems.  On the other hand, the similarities found in the evolution of prison gangs suggest that international prison systems may share some of the same failures.  Rather than working independently, officials from different countries would learn more by sharing data on prison gangs’ exploitations of varying detention systems.

2. Transnational Affiliations

International affiliations vary by gang and by region.  While MS-13 has California/U.S. connections and has been known to work with Colombian traffickers, details of such activities are imprecise.  Similarly, Brazilian prison-based gangs receive drug shipments through Suriname and Paraguay, have worked in Peru and Bolivia, and trade arms for drugs with Colombia’s FARC.  Nonetheless, the relationships between organizations from different countries are rarely clearly delineated and often only anecdotal.

By contrast, U.S./Mexico border-region gangs are transnational in nature but do not necessarily combine operations with other transnational organizations.  U.S. prison gangs primarily work within their own country.

Therefore, when prison-based gangs become large enough to participate in transnational operations, they often do so sporadically and opportunistically.  Because multi-national law enforcement presents logistical and political challenges, police officials have strong incentives to address transnational gang relationships when developing anti-gang operations.  Despite their similarities, prison gangs still operate as autonomous entities, often with independent goals.

3. Treatment of Prisoners

Prisoner abuse is common around the world.  In Central and South America, in particular, prisoner neglect and mistreatment is common practice.  Stories of abuse from behind prison walls are often met with feelings of apathy from general publics and in the absence of public outcries which might otherwise constrain their actions, prison guards outside the United States continue to mistreat prisoners, perpetuating prisoner grievances against state authority.

4. Differences in Power and Control in Prison Systems

Perceptions of de facto power and control in U.S. and Latin American prison systems vary.  In the U.S.-Mexico region, corrections officials continue to have effective control over prisons where no single gang dominates the prison population.  Differences in race and ideology divide the major strategic threat groups in the United States, preventing gangs from working together except in mutually profitable circumstances.  In all other cases, prison gangs in this region are more likely to engage in violent competition than cooperation.  Moreover, the comparatively low levels of prisoner abuse in the United States removes a potentially uniting political cause around which these gangs might otherwise coalesce.

In stark contrast, south of the U.S.-Mexico border region, prisoners often run their own prisons. Substandard living conditions, overcrowding, lack of basic amenities, and unrestrained prisoner abuse within Brazilian prisons cause inmates to pledge allegiance to gangs, such as the CV and PCC, in the hope these organizations will improve prison conditions.  Consequently, prisoners are more willing to participate in gang-orchestrated prison riots in protest of government treatment.  Poor conditions in the slums increase gang support among local populations as well, enhancing gang influence and social and economic control outside prison.  These bases of support enable gangs to disrupt cities from within penal facilities, in some cases contesting the sovereignty of the state.

In Central America, prisons have become finishing schools for criminal gangs, facilitating the recruit of new members from the inmate populations and the continued direction of operations from the inside the penal system.  In some Central American countries, such as Guatemala, gangs dominate whole cell blocks and possess de facto control over entire prisons with prison guards effectively excluded from such areas.

5. Reasons for Formation

The rationale underlying gang formation differs significantly across prison gangs in the four regions we have studied.  The majority of prison gangs formed as a means of protection from other predatory gangs, poor prison conditions, or abuse by prison authorities.  Although the specific reasons for individual group formations vary, all of the gangs eventually transformed into for-profit criminal organizations.

6. Members with Military Experience

A regional division exists in the distribution of prison gangs that have members with military experience and those that do not.  All of the observed prison gangs located in the United States and Mexico possess members who have previously served in the armed forces of their respective countries prior to entry into gang life.  The prison gangs in Central America and Brazil lack members with similar military experience.  Membership with formal military training is a major strength for prison gangs, enhancing group capacity for armed violence and self-defense.

7. Ability to Operate Without Interference from State Authorities

One of the most important differences among the various regions is the ability of prison gangs within certain states to act outside the control of the state and without interference from authorities.  Prison gangs in the United States have the disadvantage of operating in an environment of strong state control, where criminal activities must avoid detection.  In Mexico, Brazil, and throughout Central America, significantly weaker states typically lack the capacity to successfully combat the operations of prison gangs, especially in major cities.  These gangs are thus able to operate outside the control of states, often conducting criminal activities in an overt and public manner.  Gang operations in these countries are facilitated by widespread public corruption.

8. Separation of Different Gang Members in Central American Prisons

Central American prisons are unique among the penal systems described here in their inability to separate rival gang members.  In nearly all instances, this incapacity results from a lack of state resources.  While some Central American prisons are fully controlled by one gang,  many facilities are inhabited by two or more rival groups.  Where removal to separate facilities has not been an option, some prison authorities have attempted to separate the rival gangs by floor or cell.  In general, this system has been highly ineffective.  Particularly when rival gang members have been incorrectly placed in the same cells or on the same floors, prison riots have repeatedly resulted.  In Guatemala, for example, MS-13 members staged simultaneous attacks against M-18 members at seven different prisons using grenades, guns, and knives.  In the chronically underfunded and overcrowded Honduran penal system, another gang riot left thirteen inmates dead and thirty-eight injured.

9. Forced Recruitment

In Central America, recruitment of new members is critical to maintaining and increasing power for both MS-13 and MS-18 members.  Although recruitment can be voluntary, many gangs rely heavily on forced recruitment.  This Central American practice contrast sharply with the voluntary recruitment process among groups in the United States, Brazil, and Mexico.

Larger Implications: Why the Similarities and Differences Matter

1. Potential for More Inter-Gang Alliances and Operation Spillover

As the gangs under scrutiny continue to expand beyond prison walls, become more violent, and partner with one another to combat law enforcement initiatives, the possibility of increased cooperation with other criminal organizations exists.  Expanded operations lead to an expanded group of associates.  If those relationships are transnational in nature, gangs can exploit differences in national laws and police surveillance for their own advantage.  Each group’s familiarity with the prison systems of their own nation places them in an advantageous position to compare experiences.  Even when cooperation is limited to other domestic groups, prison-based gangs will benefit from exposure to additional illegal activities and trades with which their new partners are more familiar.

2. Prison Systems and Regulations Require Reform to Counter Gang Expansion

As the similarities above demonstrate, prison gangs perpetuate themselves through flaws in prison systems, benefiting from protocols with double-edge effects.  The procedure of sorting gang members away from general populations reinforces central hierarchy and control as gang populations become more concentrated, and policies meant to rehabilitate and address the needs of prisoners—family visits, religious worship, education programs, etc.—often facilitate illicit activities, for example, through the use of visitors to smuggle contraband into prisons and direct criminal actions outside.  In essence, prisons have become hubs for criminal enterprise where gangs are able to direct their for-profit operations and recruit new members to increase their power within the system.

Reform is essential both to stifle the growth of existing security threat groups and to prevent the emergence of new, younger gangs that may take the same evolutionary path of the older groups, eventually eclipsing their predecessors to seize dominance in national and transnational criminal networks.  As the Nazi Low Riders in the United States have shown, new gangs are regularly as violent and disruptive to society as the ones that preceded them, and with the concurrent evolution of modern technology and communication, they have the opportunity to become more dangerous to the state.

3. Dual Approach in Combating Prison Gangs

Authorities involved in law enforcement have been relatively successful in seeking out and arresting prison gang members in all four regions.  Gang task forces and numerous racketeering laws have been established in many regions to crack down on gang members in particular.  Once these individuals are incarcerated, however, efforts to combat gang activity are largely ended.  The analysis presented here has highlighted the need for a dual approach that not only emphasizes eliminating gangs among society at large but also stresses the need to counter gang influence inside prisons where such groups currently flourish.  Authorities must closely monitor incarcerated gang members while they are in prison and continue to expand law enforcement gang intelligence.  Few additional options exist to counter the criminal motives of gang members after incarceration.  Prison officials should focus efforts on the institution of preventative programs aimed at deterring non-gang-affiliated inmates from joining prison gangs.

4. Deportation as a Catalyst for Gang Formation in Mexico and Central America

The United States began deporting immigrants convicted of criminal activity to their countries of origin after the passage of the Illegal Immigrant Reform and Immigrant Responsibility Act (IIRIRA) of 1996.  The IIRIRA increased removals by expanding categories of deportation, restricting the ability to appeal deportation, and increasing the range of criminal offenses triggering deportation.  The U.S. government asserts that the deportation campaign is designed to target immigrants who have committed serious violent crimes; however, most removals to date have been noncriminal immigrants from Mexico and Central America.[1]  In 2008, 358,886 noncitizens were removed from the United States.  Of these, almost 69% (246,851) originated from Mexico, 29% of whom were criminals, and nearly 22% (78,726) were from Central America, 78% of whom were criminals.[2]  This mass deportation of criminals to both Central America and Mexico combined with the failure to notify national authorities of criminal backgrounds not only leaves these governments unprepared, but also places gang members largely unfamiliar with these foreign countries in a position to further identify with their gang and expand its organization.  Current U.S. deportation policies should be revised in cooperation with governments from Mexico and Central America. Reforming existing oversights will benefit affected destination countries while decreasing the likelihood of the return of criminal immigrants to the United States.

Texas Mexican Mafia (Mexikanemi)


The Texas Mexican Mafia (TMM) or Mexikanemi was formed by San Antonio native Heriberto “Herb” Huerta in 1984 at the Huntsville prison facility in Huntsville, Texas.[1]  The original purpose of the Mexikanemi was to bring Mexican nationals and Mexican Americans together in an attempt to defend against other predatory prison gangs like the Texas Syndicate.  The Texas Syndicate had preyed on weaker, non-gang-aligned Hispanic inmates within the Texas prison system, and Huerta saw an opportunity to bring together a force to combat this threat.[2]

After its creation, the Mexikanemi quickly grew into a formidable force within the Texas prison system, expanding exponentially in the gang’s first few years of existence.  As members were released, the group’s focus switched from defending itself within prison walls to becoming highly involved in criminal activities outside in San Antonio, the gang’s primary headquarters. These criminal activities included drug trafficking, extortion, murder, and robbery.  The Mexikanemi’s criminal enterprise soon spread to numerous other cities across Texas, including Houston, Odessa, Dallas, El Paso, Midland, and elsewhere.[3]

By the late 1990s and early 2000s, the Mexikanemi had become a powerful criminal force in Texas allied with numerous Mexican drug trafficking organizations.[4]  The group’s first major transnational alliances were established with the Gulf Cartel and Los Zetas, providing access to large quantities of discounted narcotics.[5]  Soon after, the Mexikanemi expanded involvement into all aspects of the drug trade, including trafficking, wholesale supply, and retail sale.[6]  By the time the Mexican Drug War escalated in the mid-2000s, the Texas Mexican Mafia had begun working for a range of drug trafficking organizations such as Sinaloa, Juarez, Gulf, and Zetas, trafficking narcotics into the United States as well as performing enforcement duties.[7]

Current Operating Situation

The Mexikanemi possesses a paramilitary organizational structure that includes a president, vice president, generals, captains, lieutenants, sergeants, and soldiers.[8]  Heriberto Huerta, the founder of the Mexikanemi, remains president of the gang and continues to run the organization from his prison cell in the supermax federal penitentiary in Florence, Colorado.[9]  Benito Alonzo is the gang’s vice-president, and Robert Carreno is believed to be the leader of the group’s outside criminal activities.[10]  Huerta and Alonzo are estimated to have close to 5,000 Mexikanemi members under their control throughout Texas and parts of northern Mexico.[11]

The gang operates under a strict hierarchy with orders disseminated through an established chain of command.  Each prison or outside region in which the gang operates falls under the control of an appointed general, vested with near-autocratic powers within the specified jurisdiction.  However, the generals must receive authorization from the president or vice president before initiating any major action.[12]  Because the Mexikanemi has members both inside and outside prison, constant communication is required between the two elements.  This is usually carried out by female members of the gang who visit incarcerated members and deliver messages to outside crews.[13]  Prison crews cannot give orders to outside crews and vice versa. When a member is discharged from prison, he must report to the general of an outside crew and continue generating income for the gang.[14]

The Mexikanemi is governed by an official constitution that establishes rules, procedures, responsibilities, and rights among members.  The constitution was written by Huerta himself in the early years of the group and is still utilized today.  According to Mexikanemi rules, membership is restricted to Mexican nationals and Mexican-Americans.  All members, including the president and vice president, bear equal obligations to the gang and every member is held accountable for his own actions.  Each member is responsible for recruiting new members into the gang, and each member who successfully recruits a new member is responsible for that person’s actions.[15]

The initiation process for the Texas Mexican Mafia is complex and well defined.  A prospective member of Mexican heritage must be recommended by an established member of the gang to the lieutenant in charge. The prospective member is then placed on a 120-day probationary period during which the recruit will be educated on gang policy and evaluated for full entry.  Probationary members must also complete gang assignments and jobs in order to prove worth and earn respect.  At the end of the probationary period, the lieutenant in charge holds a vote among established members from whom a majority vote is required to gain full membership.[16]

Overview of Activities and External Relationships

The Texas Mexican Mafia is highly active in the state of Texas.  The group’s primary source of income is derived from trafficking narcotics into the United States.[17]  Additional income is generated through the taxation of local, street-level drug dealers throughout numerous Texas cities and within prisons under the organization’s control.  Dealers who refuse to pay this 10% tax or “dime,” one of the gang’s primary sources of income, are subject to home invasions, also known as a “door kicks.”[18]  Mexikanemi members are known for their brutality, killing anyone who attempts to obstruct or limit the group’s profits.

The National Drug Intelligence Center has identified the Mexikanemi as the most powerful and influential gang operating in south Texas.  The group works with Mexican drug trafficking organizations, smuggling heroin, cocaine, methamphetamines, and marijuana across the U.S. border, primarily through the city of Laredo.  From Laredo, the drugs are taken to San Antonio, the headquarters of the TMM, and then distributed to local dealers and a network of sellers throughout south Texas.[19]

The Mexikanemi has a host of enemies throughout the prisons of Texas and northern Mexico, including the Texas Syndicate, Raza Unida, and Barrio Azteca.  Violence between the TMM and these groups is common, but differences are usually put aside in the outside world where the groups often cooperate for profit.  The Zetas Organization remains the largest external patron of the Texas Mexican Mafia and frequently works with the group.[20]

Barrio Azteca


The Barrio Azteca (BA) gang was formed inside the Texas prison system in 1986 by a group of Hispanic El Paso-based street gang members.[21]  The gang’s founders were seeking to protect themselves against other well-established, predatory prison gangs like the Texas Syndicate and the Mexican Mafia as well as to unite the Hispanic inmate population from the El Paso area.[22]  As members were released, the gang became involved in transnational crime, including a wide range of criminal activities such as drug trafficking, contract killing, extortion, human smuggling, robbery, and intimidation.[23]

Barrio Azteca members are currently housed in state and federal prisons throughout Texas and northern Mexico. The group is most heavily concentrated, however, in West Texas: the gang’s primary headquarters is located in El Paso and just across the border in Cuidad Juarez, Mexico.[24]  Barrio Azteca members are often drawn from local street gangs who join the group inside prison.[25]  Both Mexican nationals and Mexican Americans belong to Barrio Azteca, allowing for synchronized trans-border operations.

In 2003, Barrio Azteca entered into a strategic alliance with the Juarez drug trafficking organization, which hired the BA to smuggle narcotics into the United States.[26] The Chihuahua-based cartel also began to sell the Barrios drugs at a discounted price.[27]  The relationship proved useful, and the BA ultimately evolved into the Juarez cartel’s armed wing, carrying out a variety of enforcement duties and contract killings.  The Juarez organization maintains the Barrio Azteca as its primary set of enforcers today.[28]

In recent years, the Barrio Azteca gang has become well-known to law enforcement authorities alarmed at the rising levels of violence associated with the group.  In 2010, BA members murdered U.S. Consulate employee Leslie Ann Enriguez Catton and her husband, Arthur Redelf, and the husband of another Consulate employee, Jorge Ceniceros, in Juarez, Mexico.[29]  The murders were ordered by the Juarez cartel which believed that Enriguez was distributing U.S. passports to members of the rival Sinaloa cartel.[30]  Both the FBI and the DEA now list Barrio Azteca among the most pressing regional threats.[31]

Current Operating Situation

Barrio Azteca has an estimated membership of between 2,000 – 4,000 members.[32]  The organization is structured in a paramilitary-type hierarchy, with capos who lead the gang, lieutenants, sergeants, and soldiers known as “Indios.”  The capo mayor presides over the command structure and is voted in by other captains in the gang.[33]  Eduardo Ravelo is believed to be the top leader of the Barrio Azteca in Juarez, Mexico and is currently listed on the FBI’s top ten fugitives list.[34]  Ravelo came to power as a result of his close connections to Mexican drug trafficking organizations like the Juarez cartel.[35]

The Barrio Azteca gang is composed of two major factions: one based in El Paso and its surrounding areas; and another in Ciudad Juarez and its surrounding areas.[36]  The gang also has members in Chihuahua City, Midland, and Odessa.  The factions are united by a “sacred code” or rules of conduct that each member follows.  These rules demand loyalty and dedication to the gang above all else.[37]  Only the most violent of prisoners are accepted into Barrio Azteca and new members must be recommended by “padrinos” or established members.[38]  Prospect members must then gain the respect of the gang and be granted membership by the capo.  Tattoos depicting ancient Aztec symbols are used to signify gang membership and feathers are used to signify rank.[39]

Overview of Activities and External Relationships

El Paso border crossing

The Barrio Azteca gang is involved in various organized criminal activities including drug trafficking, contract killing, extortion, kidnapping, robbery, and intimidation.  Of these, drug trafficking is the group’s most profitable enterprise.  The gang is heavily dependent on its alliance with the Juarez cartel as a source for drugs such as heroin, cocaine, marijuana, and methamphetamines at a discounted price.[40]  BA members smuggle these drugs into El Paso, Texas via Ciudad Juarez, Mexico and then distribute the narcotics to retail dealers throughout Texas.[41]  The ability to successfully operate on both sides of the border is a major strength of the Barrio Azteca.

To maximize profits, the Barrio Azteca charges a tax on the drugs it provides to U.S. dealers. This street tax, called a “cuota,” is strictly enforced on turf controlled by the gang.  In turn, profits from the tax are used to further the gang’s activities and to purchase firearms and more drugs.[42]  Dealers that do not pay the cuota are often severely beaten or even killed by members of Barrio Azteca, who possess a long-standing reputation for brutality.

The Barrio Azteca has played a crucial role in the Mexican Drug War, siding with the Juarez cartel to dominate the Ciudad Juarez-El Paso drug-trafficking corridor.  Members of Barrio Azteca are often called upon to carry out hits against members of the Sinaloa cartel on behalf of the Juarez cartel in exchange for drugs, money, or weapons.  This conflict still wages on today, and in recent years, the Juarez cartel and their Barrio Azteca partners have slowly lost ground in Ciudad Juarez to the Sinaloa cartel.[43]

Mexican Mafia


The Mexican Mafia, also known as “La Eme,” was founded by Luis Flores, Mundo Mendoza, Joe Morgan, and Eddie Gonzales in 1957 at the Deuel Vocational Institution in Tracy, California.[44]  Originally, the Mexican Mafia was formed as a way to protect members from older and more hardened Hispanic, black, and white gangs.  The original members came from various street gangs in Southern California who united together for common interests and put aside their differences.[45]  As the new gang expanded its numbers, a rivalry developed between the Mexican Mafia and inmate gang members from Northern California who became known as the Nuestra Familia.[46]  These tensions still exist today and both gangs have formed strategic alliances with other gangs to strengthen their respective positions in the prison system.  Specifically, the Mexican Mafia is now allied with the Aryan Brotherhood, and the Nuestra Familia with the Black Guerrilla Family.[47]

As the Mexican Mafia grew in the Deuel Vocational Institution, prison authorities took notice and inadvertently aided their expansion.[48]  The group’s founders were dispersed to other Californian prison facilities in an attempt to break up the gang. The move, however, proved counterproductive as Mexican Mafia leaders organized new chapters, expanding the group’s influence to previously unaffected prisons.[49]  Gang members were chosen because of their Mexican heritage and proclivity for violence.  As the Mexican Mafia’s strength and influence grew, the group came to control much of the drug trafficking, gambling, prostitution, and smuggling inside the California prison system and, as members were released, increasingly in the streets of Los Angeles, San Diego and other California cities as well.[50]

In the early 1990’s, the Mexican Mafia imposed a tax on other street gangs in Southern California.[51]  This 10% tax is still the backbone of the Mexican Mafia’s empire and is mainly enforced on the Surenos, a network of California street gangs who serve as associates of the Mexican Mafia.  In addition to the tax, the Mexican Mafia established relationships with numerous Mexican drug trafficking organizations, the most important of which has been the Tijuana cartel.  The Mexican Mafia buys discounted drugs from the Tijuana cartel which the gang smuggles into San Diego via Tijuana, Mexico.[52]  The two criminal organizations still maintain close relations today.  In 2002, a high-ranking Mexican Mafia leader, Rene “Boxer” Enriquez, defected from La Eme and went on to provide authorities with high value information on gang activities and structure.[53]  The Mexican Mafia is now an organized criminal gang involved in a variety of criminal activity including murder, drug trafficking, extortion, robbery, intimidation, kidnapping, and human smuggling.

Current Operating Situation

The Mexican Mafia membership is comparatively small, believed to number a few hundred true members, but these are the most hardened Hispanic inmates in Southern California and maintain control over tens of thousands of street gang members throughout Southern California, Arizona, New Mexico, and many other states.[54]  To maintain control over such a vast empire, the Mexican Mafia utilizes extreme brutality and intimidation inside the prison system.  Other gangs accept subordinate positions in their relations with the Mexican Mafia out of fear that when their members go to prison, they will face the well-established prison gang on foreign turf.  The Surenos, a network of gangs in Southern California, function as the primary muscle of the Mexican Mafia.  These groups carry out contract killings on behalf of the Mexican Mafia and serve as drug traffickers and retail drug dealers.[55]  The Surenos pay a 10% tax to La Eme on all drug sales.  In exchange for their services, the Mexican Mafia then protects the Surenos inside prison.[56]

La Eme is loosely structured but operates according to a strict code that members must follow, though no formal constitution exists.[57]  The group is primarily made up of Mexican-American convicts and ex-convicts from the barrios of East Los Angeles.[58]  Members must be of Mexican heritage and must have killed someone prior to entry into the gang.  Status in the gang is based on the amount of time an individual has been a member and the amount of hits a member has carried out for the gang.[59]

The Mexican Mafia is organized in a hierarchical manner, but has no single paramount leader.  This structure consists of three separate parts: members, associates, and soldiers.  True members, known as “carnals,” number only about 200 and lead the gang by making all important decisions.  Associates are prospective members who carry out criminal activities for the gang.  Associates are often given command of a particular prison or outside neighborhood and can only become official members if voted in by existing gang members.  Soldiers, comprised of the thousands of Surenos responsible for enforcing Mexican Mafia authority both inside and outside prison,  make-up the backbone of the organization and perform a variety vital gang activities, for example, like collecting extortion payments for La Eme.[60]

Overview of Activities and External Relationships

The Mexican Mafia engage in a host of criminal activities such as drug trafficking, murder, extortion, intimidation, kidnapping, human smuggling, and robbery.  Drug trafficking is La Eme’s most lucrative illicit activity and is facilitated through strong connections to numerous Mexican drug trafficking organizations and unquestioned control over smuggling routes in Southern California.  The Mexican Mafia and the Arellano-Felix Organization, also known as the Tijuana cartel, cooperate in drug trafficking operations between Mexico and San Diego.[61]  Together, they move large quantities of marijuana, heroin, methamphetamines, and cocaine into Southern California for distribution to a large network of sellers.[62]  To provide the Arellano-Felix Organization access to Southern California, the Mexican Mafia charges a tax, which usually comes in the form of discounted drugs.[63]

The Mexican Mafia’s close connection to Mara Salvatrucha (MS-13) constitutes another important relationship for the group.  Like other local gangs, MS-13 is required to pay taxes to the Mexican Mafia in Southern California.  In return, La Eme provides protection for MS-13 members in prison and assists MS-13 in fighting gangs that encroach upon their territory outside.[64]  When MS-13 engages in their own drug trafficking operations through Southern California, they pay another tax to the Mexican Mafia.  Many analysts believe the “13” in Mara Salvatrucha’s name (MS-13) is a symbolic reference to the group’s close relationship with the Mexican Mafia.[65]

Extortion payments extracted from gangs and drug dealers operating in Eme-controlled prisons and neighborhoods in Southern California are the largest source of the Mexican Mafia’s revenue.  The Surenos, for example, one of the Mexican Mafia’s most important subordinate groups, are required to make payments to the gang in return for protection in prison.[66]  Gang members that refuse to pay tax to La Eme are “green-lighted” for being beatings or murder and then robbed of their assets.[67]

Regional Analysis

Transnational Latino prison gangs constitute some of the most powerful criminal organizations in the Western Hemisphere.  The influence of these groups now extends far outside prison systems into the streets and neighborhoods of many border cities.  Most of these gangs evolved from very humble beginnings to highly complex and deadly organized criminal groups with local and regional monopolies over criminal activities like drug trafficking along the U.S. border.  An examination of the Mexikanemi, Barrio Azteca, and Mexican Mafia reveals a great deal of similarities in background, command structure, and criminal activities.

Each displayed similarities in the original motivation for gang formation.  All three groups as well as other main transnational Latino prison gangs were motivated by the need for self-defense in the racially divided U.S. prison system.  Racial solidarity was seen as a way to bring Hispanic inmates together to protect against other predatory racially-organized prison gangs.  As each gang expanded, the need for a code of loyalty emerged to ensure gang cohesion.  Each gang possesses its own constitution, whether written or unwritten, detailing who is eligible for membership and what prospective members must to do to gain entry.  Violence is the most essential tool of each of these groups, and the ruthlessness of prospective members is a central criterion for consideration.  All of these gangs utilize lifetime membership in which the only way out is death.

Each of the major Latino prison gangs possesses a hierarchical command structure.  Gang leaders exercise authority through distinct chains of command.  This top down approach was modeled after the Italian Mafia, which many prison gangs look up to as the ideal criminal organization.  Leadership in all cases is centered inside the prisons where the majority of gang leaders are serving life sentences.  In spite of their incarceration, gang leaders continue recruiting new inmates and maintain contact with members on the outside.  Leadership structures, however, differ across gangs with some dominated by a single leader and others controlled by ruling-elites who make important gang decisions.

Each of the Latino prison gangs underwent a process of evolution from protective entity to criminal enterprise.  As each grew in numbers and members were released, leaders saw opportunities to capitalize off of group strengths and engage in for-profit criminal activity.  The Mexican Mafia was the first Hispanic prison gang to effectively institute a tax system based on the use of violence to extort drug dealers on the outside and prisoners on the inside.  The Mexican Mafia provides protection to street gang members, drug dealers, and average inmates in prison in exchange for a 10% tax on the illicit income of these actors.  Subsequent prison gangs have copied this approach as a successful model for turning violent propensities into profit.  All gangs engage in a variety of criminal activities including drug trafficking, murder, extortion, intimidation, and robbery, diversified criminal portfolios that effectively hedge against risks and threats to any one area through multifaceted operations.

Each of the groups is deeply entrenched in drug trafficking which constitutes the gangs’ primary source of income.  The Mexikanemi, Barrio Azteca, and the Mexican Mafia all have direct connections with Mexican drug trafficking organizations which provide narcotics at discounted prices.  All of the gangs are involved in the trafficking of marijuana, cocaine, heroin, and methamphetamines through U.S. border cities like Laredo, San Diego, and El Paso.  On the U.S. side of the border, the gangs supply these drugs to local retail sellers, who they also tax.  This drug tax is vitally important to drug trafficking operations and universally enforced with violence or the threat of violence.

Why Prison Gangs?

Prison gangs are violent non-state actors (VNSAs) engaged in a host of criminal activities directly threatening to the security and stability of countries throughout the Western Hemisphere.  Their activities run the gamut from exceptional brutality to drug smuggling and human trafficking.  The existence of powerful gangs within government prison systems, the ultimate expressions of state authority and the primacy of the rule of law, is paradoxical.  Yet not only do prison gangs exist, they thrive in confinement.  Contemporary prisons often form the epicenter of criminal activities and serve as institutions of higher learning for criminals, where ordinary and minor offenders join organized criminal groups and transform into hardened gang members and career criminals.

The growing significance of prison gangs has yet to be fully recognized among security experts.  The analysis presented here aims to reduce the ongoing disparity between the increasingly importance of prison gangs in national and transnational criminal activity and the comparative lack of expert knowledge.

The problems of street gangs and prison gangs are increasingly inextricable.  Gangs outside prison , motivated by some combination of money and fear, often carry out the dictates of powerful prison gangs and incarcerated gang leaders.  Street gangs often occupy subordinate positions in their relations with prison gangs: inevitable incarceration puts street gang members at the mercy of violent and well-entrenched prison gangs, placing a premium on good relations with the latter.  The growing reach of prison gangs parallels the broader transformation of such groups into powerful, for-profit organized criminal entities, many of whom pose increasingly transnational threats. They are the enemy within, a threat that no one suspects until it is too late and must be recognized as such.


The Federal Bureau of Investigation (FBI) defines prison gangs as:

“criminal organizations that originated within the penal system and operate within correctional facilities…although released members may be operating on the street. Prison gangs are also self-perpetuating criminal entities that can continue their criminal operations outside the confines of the penal system.”

In the United States, prison gangs are classified as Security Threat Groups (STGs).  According to the National Gang Crime Research Center (NGCRC), an STG is any group of three or more persons with recurring threatening or disruptive behavior which includes, but is not limited to, gang crime and gang violence.  The moniker of “security threat group” is intended to take away the recognition and publicity that the term “gang” connotes when referring to people who seek to undermine the system.

For the purposes of this project, the NGCRC’s definition of prison gangs will be used:

any gang (where a gang is a group of three or more persons who recurrently commit crime, and where the crime is openly known to the group) that operates in prison.

This definition is consistent with the reality that not all prison gangs originated behind prison walls.  The 2010 Small Arms Survey distinguishes between “natives” or “pure” prison gangs formed within and those “imported” into prison systems, the members of which function as “prison branches” of an organization that already established on the outside, such as MS-13 and M-18.  In practice, however, the distinction between a “native” gang and an “imported” one is often inconsequential.  The gangs observed in this analysis all utilize prisons as bases for their criminal activities and all share the same goal of undermining the laws of society.

Aryan Brotherhood (aka the Brotherhood, the Brand, the Rock, AB)


The Aryan Brotherhood was founded in California’s San Quentin maximum-security prison. Most prisons were racially segregated until the 1960s. When they were desegregated, racial violence flared and inmates formed gangs along color lines.[1] Irish bikers formed the Brotherhood to fight against the Black Guerrilla Family and Mexican prisoners. It is rumored that the Brotherhood sprung from a 1950s gang known as the Bluebirds.[2]

In the 1970s, as the Brotherhood expanded, it engaged in a race war with black and Hispanic gangs, fueled by hatred and the need for territory and profit from drug trafficking and prostitution within prisons.[3] Dozens of members were killed.[4] At this point, the Brotherhood began taking on the characteristics of a criminal organization.[5]

In the 1980s, the Brotherhood became more organized when it established a chain of command, splitting into two separate but cooperative branches: a federal prison faction and a state prison faction. The federal faction created a three-man council to direct all Brotherhood activities within federal prison, with Barry “The Barron” Mills and T.D. “The Hulk” Bingham elected as high commissioners.[6] Soon after, the state faction followed suit with a council that would supervise gang activity in the state prison system. By this time, the Aryan Brotherhood had proliferated from California, with chapters appearing in state and federal prisons across the country.[7]

In the 1990s, prison authorities began taking action against the Aryan Brotherhood. Members of the gang were moved throughout the corrections system, and the leaders were sent to the “Supermax” prisons. However, this only served to spread the Brotherhood’s influence, with members founding new chapters in more states.[8] And the criminal activities of the gang were largely unaffected, for the leaders were able to continue communication within their members through various means, including secret codes and hidden messages using urine-soaked paper.[9] Not only that, but the Brotherhood’s crimes started to escalate beyond gang grudges and prison walls. On March24, 1995, Robert Scully was released on probation from Pelican Bay State Prison, a Supermax facility. Accompanied by a female follower of the gang, Scully shot and killed a police officer six days later with little provocation, marking the beginning of the Brotherhood’s new campaign to push their murder and drug operations into the streets.[10]

In late 2002, Assistant U.S. Attorney Gregory Jessner indicted nearly all members suspected of being leaders in the Brotherhood under the Racketeer Influenced and Corrupt Organizations (RICO) Act. He charged them with carrying out stabbings, strangulations, poisonings, contract hits, conspiracy to commit murder, extortion, robbery and narcotics trafficking.[11] The intention was to produce death sentences for at least twenty-one of them, cutting off the leadership of the gang.[12] On March 14, 2006, the first in a series of gang-member trials began in Orange County, Calif., for Barry “The Barron” Mills, T.D. “The Hulk” Bingham, Edgar “The Snail” Hevle and Christopher Overton Gibson, the most powerful leaders of the Brotherhood in the federal prison system. The four were accused of ordering or participating in 15 murders or attempted murders in the last 25 years. All four were convicted, but they did not receive the death penalty.[13] Instead, they were sentenced to life in prison without parole. Even with these convictions, the criminal activities of the Brotherhood continued unabated as new, less prominent leaders took over leadership of the federal faction.

Current Operating Situation

There are approximately 15,000[14] to 30,000 members[15] within the Aryan Brotherhood, and there are chapters in almost every state and federal prison across the United States.[16] The reason for the wide disparity in numbers is due to the way the gang inducts new members. Full members, or “kindred,” recruit initiates called “progeny.” The progeny are selected from the most violent and capable inmates within the prison.[17] In order to be considered for baptism into the Brotherhood, the progeny must “make their bones” by killing someone who is targeted for death by the gang’s council.[18] Afterwards, the progeny must receive a unanimous vote from existing kindred in the “family” to be fully baptized into the Brotherhood.[19] Those who do not get a unanimous vote do not become kindred, but they remain closely associated with the gang as unofficial members.[20] Hence, the actual number of true members can only be estimated in the above range.

The Aryan Brotherhood’s ideology has evolved from its original purpose of offering protection for new white inmates from black and Hispanic prisoners in the corrections system. In the beginning, the gang was steeped in racial hatred and neo-Nazism, adopting swastikas and double lightning bolts as their symbol. New members of the Brotherhood were encouraged to read Adolf Hitler’s Mein Kampf and “make their bones” by attacking, and often killing, a black inmate.[21] As the years passed, the Brotherhood began moving away from neo-Nazism and more towards its Irish roots along with Viking/Norse symbolism and history.[22] The selection of recommended reading material expanded to include Sun Tzu’s Art of War, Machiavelli’s The Prince, and Nietzsche’s Beyond Good and Evil, The Will to Power.[23]

Rather than just protect white inmates from minorities, Brotherhood leaders have adopted a new “mission statement” that envisions that gang as “the very best criminal organization.”[24] To that end, the gang is primarily concerned with controlling the sale of drugs, gambling, and “punks” (male prostitutes) within prison walls.[25] While white supremacy is still an important part of the gang’s philosophy, some members will associate blacks and other minorities to facilitate drug transactions.[26] The gang continued to commit racially-motivated violence, but such activities became second to more profitable endeavors.[27]

Overview of Activities and External Relationships

Since the 1970s, the Brotherhood has been engaged in drug smuggling, extortion rackets, and male prostitution within the prison system.[28] In 1999, Barry Mills wrote letters to the entire gang, urging them to expand operations outside of prison in an act of “polishing the (sham)rock.”[29] To this end, the Brotherhood began enlisting paroled gang members and associates (or “Peckerwoods”)[30] to become drug dealers and stickup men[31] to set up drug rings in the streets,[32] along with committing hate crimes to maintain the Brotherhood’s reputation as a violent white supremacist group.[33] Kindred on the outside must obey the council, for they are expected to provide support to the “family” through any means.[34] Failure to do so results in death, keeping true to the oath of “Blood In, Blood Out.”[35] Profits garnered through these individuals fund the gang’s illicit activities, with money being sent into prison for the leaders’ use or sent outside to safe houses belonging to paroled members.[36]

The Brotherhood is also known to participate in gunrunning,[37] human smuggling,[38] and contract killings.[39] Some of these are committed for the gang’s own purposes, but some members of the Brotherhood deal with outside groups for profit, such as the Mexican Drug Trafficking Organizations (DTOs) who need personnel and contacts over the U.S. border and the Gambino crime family.[40]

The Brotherhood has developed a working relationship with the Mexican Mafia, originally doing so in 1971 to prevent new prison gangs from forming.[41] As a result of this cooperation, the gang actively opposes the Mafia’s long-time enemy La Nuestra Familia.[42]

Maintaining its traditional hatred for black individuals and black inmates, the Brotherhood is enemies with the Black Guerrilla Family prison gang. Additionally, they are hostile to black street gangs such as the Crips, Bloods, and El Rukins. However, as mentioned previously, the Brotherhood will set aside its racial hatred to deal drugs with black prisoners to make a profit or to incite a prison riot.[43]

The allies of the gang include the Nazi Low Riders, Public Enemy Number 1 (PENI),[44] inmates hailing from motorcycle gangs, and the Dirty White Boys.[45] The Brotherhood cooperates with the Nazi Low Riders and the Dirty White Boys to augment their strength and to help facilitate drug trafficking in prison should Brotherhood members be incarcerated.[46]

In its relations with “copycat” gangs that use its brand, members of the Brotherhood usually tolerate them. However, federal and California state members do not consider them to be legitimate and may threaten violence if gang tattoos are not burned or cut off.[47]

Black Guerrilla Family (BFG)



The Black Guerrilla Family was founded in California’s San Quentin state prison in 1966 by George Lester Jackson, W.L. Nolen, James Carr, and other racist black inmates.[48] Originally called the Black Family and the Black Vanguard, Jackson’s gang was first the Revolutionary Armed Movement that aligned with the Black Panther Party. Jackson then merged with James “Bone” Johnson’s group called the Black United Movement and these groups formed the early BGF.[49]

The gang’s founding fathers were innate writ writers[50] who adopted a Marxist/Maoist/Leninist revolutionary organization with stated goals of eradicating racism, struggling to maintain dignity black prisoners, and overthrowing a U.S. government[51] perceived as a racist white institution.[52] Some were former members of Black Liberation Army, Symbionese Liberation Army, and Weatherman Underground organization.[53] Jackson became a revolutionary in prison and wrote several books including “Soledad Brother – The Prison Letters of George Jackson” and “Blood in my Eye.” The following was typical of what Jackson preached:

“Settle your quarrels, come together, understand the reality of our situation, understand that fascism is already here, that people are already dying who could be saved, that generations more will die or live poor butchered half-lives if you fail to act. Do what must be done, discover your humanity and your love in revolution. Pass on the torch. Join us, give up your life for the people.”[54]

On January 13, 1970, Nolen was killed by guards during a bloody prison riot where the BGF fought the Aryan Brotherhood in Soledad State Prison.[55] Later that year, on August 7, 1970, George Jackson’s younger brother, Jonathan, led BGF militia members into storming the Marin County Courthouse in San Rafael, California in an attempt to free Jackson who was on trial for capital murder.[56] They tried to take Judge Harold Haley hostage, causing law enforcement officials to open fire. The judge, a bailiff and 1 BGF member were killed in the shootout. George Jackson survived but was swiftly apprehended and sent to the maximum security San Quentin State Prison.[57] The BGF had expected assistance from the Black Panther Party that never materialized, leading to a rift between the two groups.[58]

Jackson was killed while attempting to escape from San Quentin’s Adjustment Center-High Security Unit in August 1971.[59] With the main founders dead, BGF members lost morale and began moving away from the previous Communist-Mao ideology of the gang. The new leader, Ruben Williams, did not possess any political vision; he was more interested in robbery, extortion, and drug trafficking.[60]

In August 17, 1980, leaders of the BGF ordered the murder of two black inmates at the Vacaville, California State Prison, violating their principal rule of prohibiting the shedding the blood of fellow black people.[61]

On August 22, 1989, Huey P. Newton, co-founder and leader of the Black Panther Party, was killed by a BGF drug dealer named Tyrone Robinson. Relations between the two groups had been at a low point ever since the Black Panther Party failed to assist the BGF in freeing George Jackson. In addition, Black Panther members who had joined the BGF in prison were disenchanted with Newton over his perceived abandonment of Black Panther inmates and allegations of fratricide within the party.[62] Newton gained the BGF’s animosity from extorting local BGF drug dealers to obtain free drugs in order to feed his cocaine addiction.[63] The leaders of the gang then ordered Newton’s death after he began demanding that the BGF stop selling heroin to black addicts.[64]

The BGF began to decline during the 1990s, but it recovered its membership through recruiting from black street gangs such as the Crips and the Bloods.[65]

Current Operating Situation

The Black Guerrilla Family is the most “politically” oriented of the major prison gangs in that it was formed as a Marxist/Maoist/Leninist revolutionary organization.[66] Its ideological doctrine considers all blacks political prisoners, and it has attempted to organize black advocacy by the imposition of their commands upon other inmates. Members hold cultural unity, group protection and the promotion of armed revolution above all else. Their reading material includes George Jackson’s Prison Letters and The Anarchist Cook Book, as well as various works from Mao Zedong, Eldridge, Ho Chi Minh, and Malcom X.[67]

The BGF communicates its message of revolution through various means, such as selling motivation t-shirts with the slogan “Revolution is the Only Solution.”[68] One tool of propaganda is The Black Book: Empowering Black Families and Communities. This 122-softbound publication was written by Eric Marcell Brown, the leader of the Maryland BGF, and is published through Dee Dat Publishing.[69] There is an online order form that offers discounts to inmates.[70] The book seeks to make people aware of the vision of “Comrade George Jackson” and calls for political and economic liberation for blacks. It is used as a recruiting tool in prisons, and the proceeds from book sales fund the BGF’s activities.[71] Within the book, Brown writes that the BGF organization is a movement (not a gang) that seeks to relieve the plight of blacks in the community.[72]

While it has spread across the U.S. in both the federal and state prison systems, the BGF is predominately focused on the East and West coasts. They are especially strong in the state of Maryland where the gang has spread to the streets of Baltimore to threaten the community and law enforcement.[73]

The BGF gang is organized along a paramilitary line, adhering to the Marxist political ideologies of Mao Zedong.[74] Each prison has a central committee, with a “supreme leader,” which issues orders to members in the area.[75] The size of the gang consists of 100 to 300 true members[76] with about 50,000 associated members.[77] The reason for such high membership is that the BGF traditionally recruits black prisoners from street gangs.[78] While most gangs, like the Crips, do not believe in the BGF’s calls for revolution against the state, they join with the prison gang out of need for protection and profit.[79] These recruits keep their association with their original gangs, so they are not true members of the BGF.[80] Initiation requires nomination from an existing BGF member and a strict oath of lifelong allegiance, with death as the only exit option.[81]

Overview of Activities and External Relationships

The BGF engages in drug trafficking and smuggling in and out of prison. Gang members on the outside, as well as family members of inmates, use a variety of means of getting drugs and other contraband—including cell phones—into the prison. These couriers hide items in body cavities or in hidden compartments in their shoes. They then switch shoes with inmates during visits.[82] Other smuggled goods may include liquor and food for BGF leaders. Eric Brown was known to eat lobster and drink Grey Goose vodka while behind bars.[83]

Being an extreme anti-government and anti-official group, the BGF use smuggled cell phones to direct attacks against fellow inmates and corrections officers. Members communicate on whether one of their own is arrested or is suspected of cooperating with law enforcement. They place “hits” on traitors and organize attacks to further the gang’s activities, including robberies of drug dealers and assaults on rival gangs.[84]

The BGF runs extortion rackets that rely on corrupt corrections employees to function. Not only do these recruited employees add to the volume of smuggled contraband into prisons, but they also facilitate the gang’s financing operations. Inside the Maryland prison system, BGF members use violence and threats of violence to coerce other prisoners to pay protection money to the gang. The BGF would then give the extorted inmate a credit card number of a prepaid credit card, sometimes called a “Green Dot” card, and would direct the inmate to have family and friends place money on the card when order to do so. A gang member on the street or a BGF-affiliated corrections officer usually holds the credit card, using it to buy goods and drugs for the gang. If the threatened inmate does not agree to be extorted, he is targeted for violence. “Green dot” cards are often used in prison as a form of currency, in lieu of paper money.[85] Corrections officers do business with the BGF for several reasons, sympathy and bribery being chief among them. Such officers are marked with tattoos of stars, butterflies, and beetles on a part of their body to identify themselves to gang members.[86]

The BGF has a very active working relationship with La Nuestra Familia, whom it allied with in 1970 to battle the Mexican Mafia and the Aryan Brotherhood.[87] These two prison gangs are still its enemies in the present day, warring over territory and racial issues. KUMI 415 Nation are known to be employed as enforces for the gang.[88] Allies that the BGF can call upon are usually black gangs or groups, such as the Black Liberation Army and Weather Underground.[89] Black street gangs (Crips, Bloods, etc.) are an important resource for the BGF, for they supply new recruits when they are sent to prison, and they provide a wider network of contacts outside of prison, making the conduct of illegal activity easier. Additionally, street gang members who have had military training can add their expertise in weapons and killing to skills available to the BGF.[90]

The BGF has been known to established ties with Mexican DTOs (specifically the Sinaloa DTO),[91] performing arms, drug, and human smuggling across the border. Gang members may even do contract killings or intimidate rivals for the drug cartels.[92] All of this is done to benefit the gang financially.

Nazi Low Riders (aka NLR, “The Ride”)


The Nazi Low Riders trace their origins to the Aryan Brotherhood (AB). In the late 1970s and early 1980s, the California Department of Corrections was actively cracking down on the Brotherhood, incarcerating members in isolation in Security Housing Units (SHUs) in an attempt to break up the gang’s activities.[93] With the official designation of prison gang place upon them, AB members found it difficult to conduct their business, especially drug trafficking, their main source of income.[94] Needing middlemen to help facilitate their criminal operations, AB leader John Stinson recruited young skinheads incarcerated by the California Youth Authority at the Preston Youth Correctional Facility, in Ione, and at the Youth Training School, in Chino.[95] The gang had just begun to establish itself with the mission of providing protection for white inmates and ridding the streets of blacks,[96] and it took its name from “low riders,” a phrase associated with Hispanic gangs.[97] The main benefit for the Brotherhood was that the Nazi Low Riders had not yet been classified as a prison gang, and thus were not under the scrutiny of the corrections system. This made the new gang suitable to act as junior partners to the Aryan Brotherhood, taking orders from the more senior and frightening gang and serving as errand-boys and enforcers.[98]

The NLR led a relatively uneventful existence for several years, operating under the radar of law enforcement until the early 1990s. By then, the California Department of Corrections had successfully disrupted and virtually suppressed AB’s activities. NLR’s role as middleman for its predecessors’ criminal operations put it in position to take the older organization’s place in the prison gang hierarchy, and it became the principal white gang in California’s penitentiary system.[99]

Current Operating Situation

Today, the NLR is officially classified as a prison gang, with corrections officials using that distinction to lock members away in isolation in the same manner as their AB predecessors.[100] While the gang still derives much of its power from inside prison facilities, it is also a significant street gang. After first coming to the attention of authorities in Costa Mesa, California, other units appeared throughout California. Recently, paroled NLR members have moved east to spread the gang’s influence, with “affiliates” growing quickly in several states throughout the U.S.[101] During the past several years, NLR’s well-run and often extremely violent criminal operations have established it as a major player in the West Coast criminal world and among white supremacist skinhead gangs.[102]

There are about 1000 members in the gang, organized in a three-tier hierarchy consisting of “seniors,” “juniors,” and “kids.”[103] Seniors lead each NLR prison unit, some of whom have been connected to the gang since its early days in the California Youth Authority. To attain senior status, NLR members must have been active for at least five years and must be elected by three other senior members. In the hierarchy, juniors, who are just below seniors, cannot induct new members (only a senior can confer membership), but they recruit potential members, who are required to have proven criminality and loyalty to the white race.[104] The senior who inducts a kid becomes his mentor and disciplinarian. Kids usually come from smaller white power gangs such as the PEN1.[105]

In contrast to its strict prison hierarchy, NLR’s street leadership structure is unclear. Members organize locally only with the approval of established leaders—those who try to set up independently risk retribution. Recruits from the outside are usually culled from smaller white gangs like Insane White Boys, La Mirada Punks, Independent Skins and Orange County Skins, all of whom acknowledge and submit to NLR’s authority on the street. Some law enforcement officials believe that NLR hopes to unite all white gangs under its umbrella and, much like ethnic organized crime rings, tax the proceeds from their criminal operations — with the collections sent to incarcerated NLR members.[106]

The NLR’s current ideology is more driven by profit than by white power beliefs, although members continue to commit violent acts against minorities to keep up their reputation.[107] The profit mentality is clearly expressed in the gang’s unusual characteristic of allowing small numbers of Latinos to join despite the NLR’s avowed racism, although there is a stipulation that the Latino inductees must be half-Caucasian, and they must show loyalty to the white race and hatred for blacks and “race traitors”— those in interracial relationships or who demonstrate an affinity for what members consider to be black culture.[108] Latino last names and girlfriends are permitted. The advantages that the Latino members confer upon the gang are increased manpower and participation in much of the dirty work of trafficking drugs such as highly addictive methamphetamines inside and outside of prison.[109] Other nonwhites are forbidden from joining.[110]

A rift is being created with the NLR due to the inclusion of Latinos. Prison officials have noticed two factions in the Nazi Low Riders: one that supports its older, partially Latino membership, and another that only wants pure white members, like their patrons in the Aryan Brotherhood.[111] Michael “Snake” Bridge leads the faction that wants to abandon ties with the AB, while Joseph “Blue” Lowry wants a more rigid ideology,[112] calling for ending members’ drug use and expelling “race traitors” from the gang.[113]

Overview of Activities and External Relationships

The NLR engages in criminal activity such as robbery, murder, and extortion, but it primarily finances itself through the manufacture and trade of methamphetamines (also called “meth” or “speed”), and they.[114] Speed is relatively easy to produce and is both in high demand and very profitable. Members jury-rig “meth labs” wherever they can, from million-dollar homes to motel rooms. The gang has created several labs in San Bernardino; in Orange County, the Antelope Valley and Riverside, NLR has become a major distributor of the drug. It is also likely that NLR works with motorcycle gangs in methamphetamine production and distribution.[115] A side effect of their involvement in drug trafficking is that NLR members are often addicted to speed they sell, making them known as “tweekers.”[116] While this increases their proclivity toward violence in prison and the streets, it also may keep them from organizing more effectively.[117]

Women have an important place in the NLR. They oversee the gang’s business operations while their men are incarcerated.[118] Often family members or girlfriends of NLR members, they have sometimes become directly involved in the violent activities of the gang, including being accomplices in murder.[119] More commonly, however, the female members act as liaisons to speed users unaffiliated with the NLR, supplying addicts with drugs and sexual favors. Eventually, NLR members coerce these users, through force and intimidation, to commit crimes for the gang. Sometimes, NLR members rob the addicts themselves, knowing that the victims will not report the incidents to the police due to their own criminal activity.[120]

Outside of prison, NLR members tend to congregate in pool halls, bars, fast-food joints, video arcades and high schools, where they try to recruit new members.[121] In some communities, NLR members live together in the same apartment buildings. These NLR clusters often serve as family-like units for alienated and uprooted young men. Although the NLR does not fight other gangs over turf, it does tend to dominate the areas where members live. When NLR members move into a residential complex, they often establish themselves by harassing or threatening other residents.[122]

As mentioned in the above paragraphs, the NLR recruits from small white power gangs in prison and on the street. The gang has a particularly close relationship with Public Enemy Number One (PEN1) because of prison crackdowns.[123] By 1999, the NLR was responsible for a large part of the violence in California prisons, causing prison officials to classify the group as a “disruptive gang,” authorizing more restrictive treatment and isolation of suspected gang members.[124] Furthermore, in 2003, after four years of investigation, indictments were finally handed down against several NLR leaders for alleged violations of RICO.[125] While the leadership could still communicate using “kites”—prison slang for letters—in nearly indecipherable runic alphabets, they found that their ability to conduct narcotics sales, extortion and other criminal activities in prison were severely impeded.[126]

Following the example of the AB, the gang turned to a smaller gang, PEN1, to help maintain its criminal operations.[127] Founded by inmate Donald “Popeye” Mazz with about 350-400 members,[128] PEN1 shares NLR and AB’s racism, and specializes in drug dealing and identity theft. It has since taken over gang jobs for both the NLR and the AB. It is not uncommon for all three gangs to cooperate in prison riots and the drug trade.[129]

The NLR is suspected of colluding with Mexican DTOs in drug and human smuggling due to its association with the AB.[130]

Dead Man Incorporated (aka DMI)


Perry Roark formed The Dead Man Inc. in the Maryland Department of Corrections about the late 1990’s. Roark, a white man who was close friends with black inmates, had wanted to join the Black Guerilla Family, but he was rejected as he did not fit the racial requirement.[131] Because he was respected among several BGF members, he was allowed to form Dead Man Inc., along with co-founders James Sweeney and Brian Jordan, with the BGF’s blessing.[132] Intended as a white off-shoot of the BGF, the gang adopted the BGF’s basic philosophy which is anti-government and anti-authority.[133] The DMI offered white inmates another path other than white supremacy movements, and its membership grew to include prisoners from those organizations.[134] Members began to conduct gang business for the BGF, committing acts of violence and murders for payment.[135]

Current Operating Situation

DMI has a reputation for violence and a willingness to carry out attacks for drugs and money.[136] In recent years, corrections officials tried to break up the gang’s operations by sending co-founders Sweeney and Jordan to other prison facilities. Roark currently resides in the Maryland Correctional Adjustment Center, while Sweeney and Jordan are in Texas and Louisiana, respectively.[137] However, this only served to expand the gang’s influence to those states and several others.[138] The Supreme Commanders, the original founders, lead the DMI in a paramilitary structure with commanders placed in each prison.[139]

There are approximately 10,000 DMI members nationwide,[140] with 500 members in Maryland alone.[141] But this large membership has brought a crisis in the gang. In the beginning, there was a careful screening process for new recruits,[142] but as the years passed, the gang grew rapidly as it absorbed smaller gangs until it became the third largest gang in the Maryland prison system.[143] As result, there was an influx of new members who did not support DMI’s core values and would not defend each other in fights. They even attacked each other in prison, causing trust problems to develop in the gang. To address the issue, Roark declared that all rule-breakers and illegitimate members must leave DMI by 4/13/09, the numbers representing the gang’s initials in the alphabet.[144] The effects of any purge on the membership are currently unknown.[145]

There is another conflict brewing within the gang concerning the direction DMI should take in the future. Roark wants to maintain ties the BGF, the group’s original patron. While in Texas, co-founder Sweeney associated with the Aryan Brotherhood of Texas and formed his own splinter faction, the Power Over All gang. Sweeney desires that all of DMI swear allegiance to the white extremism doctrine of his gang.[146]

Hence, law enforcement officials believe that DMI has or will reach a turning point in its history in the near future.[147]

Overview of Activities and External Relationships

DMI is active in and out of prison. Being an off-shoot of the BGF, the organization commits many of the same criminal activities. DMI members engage contract killings,[148] violent crimes, armed robbery, drug trafficking, and extortion.[149] They even utilize the same tactics in communication, issuing orders to members in and out of prison with contraband cellphones.[150]

While they take jobs from the BGF, DMI members are known to offer their services to other gangs, targeting rival groups and corrections officers for money.[151]

Regional Analysis

Leadership is an important aspect in the evolution of the security threat groups (STGs) observed in the U.S. In the beginning, the STGs formed as a means of self-defense for whites and African Americans who sought protection against rising racial tensions in the prison system. At first, racial gangs engaged in typical criminal behavior, inciting attacks against rivals and struggling for control of the drug trade within the walls. But, over time, the senior leadership of the STGs made crucial decisions regarding the future of their gangs. AB leader Barry Mills directed the Brotherhood to expand its drug operations outside prison walls for the first time in 1999, extending the gang’s criminal network into the streets of communities, and Ruben Williams of the BGF took his gang in a new direction that emphasized drug trafficking and profit after the previous revolutionary leaders were killed. Through the power of reward and coercion,[152] gang leaders enforce discipline among the ranks inside and outside of prison thanks to the centralized hierarchies of the major gangs.

It would make sense to indict leaders on racketeering charges under the RICO Act and isolate them within maximum security prisons, but this has not worked within the U.S. so far. Gang commanders always find ways to communicate with their members, whether it be through secret messages or corrupt corrections officers. Furthermore, targeting leaders only disrupts a gang’s illicit operations in the short-run. The major gangs are extremely resilient in the face of pressure from state authorities. New leaders will appear to take the place of the incarcerated, and recruitment continues unabated within the walls. This is due to the fact that, in focusing on cracking down on gangs inside and outside of prison, the state authorities do not address the root causes of prison gangs in the U.S. As it did the past, racial tension and conflict drive the formation of security threat groups in the present day.[153] New inmates will naturally seek out those of their own race for protection and money, or else gangs of a different ethnicity will attack or extort them.[154] As long as the issues of racism continues to divide people, prison gangs will not be going away in the foreseeable future unless certain reforms are enacted in the U.S. corrections system.

Security threat groups in the U.S. have shown the ability to replicate themselves or more of their kind to an extent. The Aryan Brotherhood begat the Nazi Low Riders because they needed middlemen in their drug trafficking business after the prison authorities locked down their own members. Over time, the NLR’s power and influence in the system grew, and they suffered the same fate as the Brotherhood when corrections officials began cracking down on their activities. In response, the NLR in turn begat a smaller gang named Public Enemy Number One to handle their criminal business inside the walls. It can only be assumed that when PEN1 reaches a certain point, it too will establish a new gang to carry on its work.

However, not all replication is successful. The Black Guerilla Family spawned an offshoot in the form of Dead Man Inc., which is a white gang that was modeled after a black gang. Unlike the NLR, DMI expanded too quickly and experienced discipline problems within its ranks, with distrust and infighting threatening to destabilize the gang. In addition, DMI is split into factions based on what direction the different leaders want to take the group. While the NLR has the same problem of factions, there is little evidence showing that its members come to blows over the issue, unlike the members of DMI who are known to attack each other due to interpersonal disputes.

The major prison gangs in the U.S. are increasingly conducting business with Mexican Drug Trafficking Organizations (MDTOs) to generate profit to fund their own operations. White supremacist gangs like the Aryan Brotherhood have the tendency to overlook racial differences when they see the color of green. MDTOs will typically hire prison gang members to do alien smuggling, human and drug trafficking, gun running, kidnappings, and contract killings across the US border.[155] These gang members are valuable due to their U.S. citizenship and their ability to cross the border without much scrutiny.[156] In return for their services, the prison gangs can buy large quantities of drugs at low prices directly from the MDTOs, granting them greater control over the wholesale drug market due to the removal of mid-level buyers.[157] In addition, the developing relationship between prison gangs and Mexican DTOs can lead to the emergence of new gangs in the U.S. The Mexican government extradites DTO members to face charges north of the border. These members are placed in federal prisons where they receive protection from security threat groups with whom they have had previous dealings.[158] While incarcerated, the MDTO personnel are in position to form their own gangs to extend their illicit crime network into the U.S.

Prison gangs could pose a serious threat to the security of the U.S. in the future. According to a survey conducted by the National Gang Intelligence Center, only 15.8% of law enforcement officials viewed prison gangs as a significant threat. Comparatively, 45.3% viewed neighborhood street gangs as a significant threat. This implies that, on their own, prison gangs are not a threat, but if one takes into account that these gangs often control street gangs through intimidation and violence inside prison,[159] then the threat level of prison gangs increases due to their capability to command the operations of the gangs on the streets. These criminal networks of security threat groups and street gangs are mainly decentralized, which differentiates them from the more centralized MDTOs that are vulnerable to law enforcement agencies (IF they are well-funded and deployed effectively).[160] The advantage of decentralization is that if one gang is taken down, the greater network survives.

Yet, it is unlikely that prison gangs will threaten U.S. security. While security threat groups will continue to pose challenges to law enforcement and public safety, they do not have the means to overthrow state and federal government. The nature of decentralized networks, being composed of many disparate groups, makes it difficult for prison gangs to challenge state power in a coherent way, especially when they have no higher political ambitions to unite them other than profiting off of the drug business. Besides, the different gangs in the network have their own motivations, and they may rebel against the security threat group in charge for their self-interest. Thus, unless they evolve into new forms in the future[161] or cooperate to achieve a social good, U.S. prison gangs are currently not a threat to U.S. security for the foreseeable future.
