In a ranch south of Texas, the man known as The Executioner dumps five hundred body parts in metal barrels. In Brazil's biggest city, a mysterious prisoner orders hit-men to gun down forty-one police officers and prison guards in two days. In southern Mexico, a meth maker is venerated as a saint while enforcing Old Testament justice on his enemies.

A new kind of criminal kingpin has arisen: part CEO, part terrorist, and part rock star, unleashing guerrilla attacks, strong-arming governments, and taking over much of the world's trade in narcotics, guns, and humans. What they do affects you now--from the gas in your car, to the gold in your jewelry, to the tens of thousands of Latin Americans calling for refugee status in the U.S. Gangster Warlords is the first definitive account of the crime wars now wracking Central and South America and the Caribbean, regions largely abandoned by the U.S. after the Cold War. Author of the critically acclaimed El Narco, Ioan Grillo has covered Latin America since 2001 and gained access to every level of the cartel chain of command in what he calls the new battlefields of the Americas. Moving between militia-controlled ghettos and the halls of top policy-makers, Grillo provides a disturbing new understanding of a war that has spiraled out of control--one that people across the political spectrum need to confront now.

In a secret meeting in 1981, a low-level Boston thief gave career gangster Ralph Rossetti the tip of a lifetime: the Isabella Stewart Gardner Museum was a big score waiting to happen. Though its collections included priceless artworks by Rembrandt, Vermeer, Degas, and others, its security was cheap, mismanaged, and out of date. And now, it seemed, the whole Boston criminal underworld knew it.

Nearly a decade passed before the Museum museum was finally hit. But when it finally happened, the theft quickly became one of the most infamous art heists in history: thirteen works of art valued at up to $500 million, by some of the most famous artists in the world, were taken. The Boston FBI took control of the investigation, but twenty-five years later the case is still unsolved and the artwork is still missing.

Stephen Kurkjian, one of the top investigative reporters in the country, has been working this case for over nearly twenty years. In Master Thieves, he sheds new light on some of the Gardner’s most abiding mysteries. Why would someone steal these paintings, only to leave them hidden for twenty-five years? And why, if one of the top crime bosses in the city knew about this score in 1981, did the theft happen in 1990? What happened in those intervening years? And what might all this have to do with Boston’s notorious gang wars of the 1980s?

Kurkjian’s reporting is already responsible for some of the biggest breaks in this story, including a meticulous reconstruction of what happened at the Museum museum that fateful night. Now Master Thieves will reveal the identities of those he believes plotted the heist, the motive for the crime, and the details that the FBI has refused to discuss. Taking you on a journey deep into the gangs of Boston, Kurkjian emerges with the most complete and compelling version of this story ever told.

Master storyteller Marc Mappen applies a generational perspective to the gangsters of the Prohibition era—men born in the quarter century span from 1880 to 1905—who came to power with the Eighteenth Amendment.

Making use of FBI and other government files, trial transcripts, and the latest scholarship, the book provides a lively narrative of shootouts, car chases, courtroom clashes, wire tapping, and rub-outs in the roaring 1920s, the Depression of the 1930s, and beyond. Mappen asserts that Prohibition changed organized crime in America. Although their activities were mercenary and violent, and they often sought to kill one another, the Prohibition generation built partnerships, assigned territories, and negotiated treaties, however short lived. They were able to transform the loosely associated gangs of the pre-Prohibition era into sophisticated, complex syndicates. In doing so, they inspired an enduring icon—the gangster—in American popular culture and demonstrated the nation’s ideals of innovation and initiative.

There has been growing concern among policy makers and the wider public about the continued spate of high profile murders involving firearms, along with a perception that these events are a result of youth gang violence more generally. These incidents have been taking place in major cities across the UK, including Liverpool. This perception of escalating violence among young people, frequently involving weapons, has prompted the government to make confronting what it has termed ‘gun, knife and gang crime’ a priority. However, relatively little information exists on ‘gang’ involvement and ‘gun crime’, who is committing it, for what reasons and what might be the best ways of reducing it. Other commentators have connected gun crime to criminal gangs and a growing ‘gang culture’ as an overarching explanatory variable, nevertheless, important gaps remain in our knowledge about violent crime fuelled by gangs and weapons. This research study draws upon an extensive literature review of the national and international research examining gangs and gun crime, coupled with a series of in-depth interviews with senior practitioners, senior specialist police officers, front line youth workers, and gang and gun involved young people from across Liverpool.

Over the past decade, youth gangs have come to constitute a serious problem for public security in Central America. The situation has generated increasing levels of fear among the general population and has become a theme of great concern also within government circles. This has been the case in particular for the countries located in the region’s northern triangle – El Salvador, Honduras and Guatemala. However, also Nicaragua and Costa Rica have, to some extent, experienced a similar development concerning the growth of violent and criminal youth gangs. While the existence of criminal youth gangs is not at all new in Central America, the systematic use of violence and the brutality shown by the new type of gangs is no doubt unprecedented – something which today is embodied in the very concept of the maras. Although it would be incorrect to make the maras the main culprits for the rapid increase of violence during recent times in Central America, they clearly do represent a major and very real problem which deserves greater attention in order to improve both the security situation for the citizens and future prospects for the region’s youth. History as well as social sciences show that youth delinquency is primarily a group phenomenon refl ecting complex social and economic situations. Consequently, for the design and carrying out of effective and successful action programs profound, specifi c and updated knowledge is required. It is in this context that the Swedish International Development Cooperation Agency (Sida) – with support also from the Central American Bank for Economic Integration (CABEI) – decided to fi nance a regional and multi-disciplinary study on the maras and other violent youth gangs, an applied study with a solid empirical base and characterized by a contextual approach focusing not only on the gangs but bringing into the picture also the neighbours, the local community and the police. The objective of the present publication – which constitutes a condensed version of the study carried out by a team of researchers from the company Demoscopía S.A. – is to facilitate a more comprehensive as well as constructive and action-oriented public discussion, concerning both the need to immediately address the current situation and to develop policies and measures for prevention.

Why do people leave a group that they have been a member of? What do they do to leave their group? What role, if any, do the use of social media and the Internet play in this process? These are central questions that motivate our interest in desistance. In criminology the focus on desistance has been a part of the life course study of crime. This approach examines involvement in crime across the life span, and pays particular attention to initial involvement in crime during adolescence as well as declines in crime that tend to occur beginning in the early twenties. This latter process is referred to as desistance from crime and tends to occur rather rapidly, usually starting in the late teens. This is typically a period of considerable maturation, marked by the movement from adolescence into adulthood and the increasing involvement in family and the labor market. Social media play an increasingly important role in the lives of adolescents as they transition to adulthood.

This summary integrates the findings of seven data- collection and research phases conducted in the initial assessment of the National Youth Gang Suppression and Intervention Program. Due to methodological problems, the scope and seriousness of the youth gang problem are not reliably known. Law enforcement and media reports, however, suggest that criminal youth gangs are active in nearly every State as well as in Puerto Rico and other U.S. territories. The close relationship of gangs, violence, and a significant crime problem are most evident when the criminal records of youth gang members are compared with those of youths who are not in gangs. Youth gang membership is associated with significantly higher levels of delinquency and index crimes. This report considers the characteristics of gang structure, the social contexts in which gangs emerge, emerging and chronic gang problems, and strategic responses. The five basic strategies that have emerged in addressing youth gangs are neighborhood mobilization, social intervention, provision for social and economic opportunities, gang suppression and incarceration, and an organizational development strategy. A discussion of institutional responses focuses on the police, prosecution, the judiciary, probation/parole, corrections, schools, community organizations, and employment. Policies and procedures, as well as promising approaches, are also summarized. Common elements associated with reducing the youth gang problem for significant time periods include clear recognition of a youth gang problem, proactive leadership by representatives of significant criminal justice and community-based agencies, mobilization of both formal and informal community networks, and a focus on community activities that contribute to positive youth development.

Government officials in northern Central America (Guatemala, El Salvador, and Honduras) claim the Mara Salvatrucha (MS-13) and Barrio 18 are primarily responsible for violence in their countries. These gangs have been identified to exert violence, extortion rackets, and confront security forces that enter gang-controlled communities (Seelke, 2014; Natarajan et al, 2015; International Crisis Group, 2017; Servicio Social Pasionista (SSPAS), 2017; Insight Crime and Asociación para una Sociedad mas Justa (ASJ) [Association for a more Just Society] 2016, Arce, 2015). But exactly how do gangs contribute to violence and extortion rackets in these countries? What are the differences, if any, on how the gangs commit these crimes in Guatemala, Honduras, and El Salvador? This working paper discusses the complex violence dynamics in northern Central America and argues that a chronic deficiency in data, weak rule of law, and impunity exacerbate insecurity in these countries. The Mara Salvatrucha (MS-13) and Barrio 18 originated in Los Angeles, California and are now present throughout the United States, northern Central America, Spain, and Italy (Franco, 2008; Valdez, 2009; Seelke, 2016; Valencia, 2016; Finklea, 2018; Dudley & Avalos, 2018). Barrio 18 was formed in the 1960s by mixed-race Mexican, and MS-13 was formed in latter 1980s by Salvadorans who fled the civil war (Franco, 2008; Valdez, 2009; Seelke, 2016; Wolf, 2012). Some scholars argue gang culture was exported when individuals with criminal records were deported to their country of origin, while other scholars argue voluntary migration contributed to gangs’ presence in northern Central America (Arana, 2005; Franco, 2008; Seelke, 2016; Cruz, 2010). It is imperative to clarify that a criminal removal from the United States is not synonymous, nor does it imply a perfect correlation with a gang member being removed. Nonetheless, these gangs have become major security concerns in northern Central America. This study examined the concentration of crimes often attributed exclusively to gangs (homicides, extortion, and confrontations) using administrative data from the Salvadoran National Civilian Police, Honduran Prosecutor’s Office, and Guatemalan National Civilian Police. Interviews with subject matter experts supplemented the quantitative analysis to gain further understanding of violence dynamics per country. This paper follows with a literature review on homicides, extortion, and confrontations trends in northern Central America, a methodology section, results, and a discussion.

A new Center for Immigration Studies Backgrounder finds that immigration law enforcement has been highly effective in fighting gang activity around the country. Local law enforcement agencies that shun involvement with immigration law enforcement are missing an opportunity to protect their communities, according to the authors. Since 2005, ICE has arrested more than 8,000 immigrant gangsters from more than 700 different gangs under an initiative known as Operation Community Shield.

The Backgrounder, “Taking Back the Streets: ICE and Local Law Enforcement Target Immigrant Gangs,” by Jessica M. Vaughan and Jon D. Feere, was funded by the Department of Justice and describes the unique public safety problems posed by immigrant gangs. The authors present previously unpublished statistics on gang arrests by Immigration and Customs Enforcement (ICE), describe how immigration law enforcement authorities are used to combat gang activity, and offer policy recommendations to improve federal-local cooperation, and without damaging relations with immigrant communities.

This paper follows the beginnings of one of the most notorious transnational street gangs in existence today. We will trace the growth of Mara Salvatrucha (MS-13) from their emigration from El Salvador to Los Angeles, California. El Salvador had just suffered a civil war that had claimed an estimated 100,000 people. This gang’s transformation from a local sureno street gang (southern street gang) to a transnational gang happened when the United States got tough on immigration laws and deported many of these MS-13’s back to El Salvador. At this juncture, they used their knowledge from what they had learned back in the U.S. and created the MS-13 in Central America and Mexico. This paper will prove from the research just how the MS-13 and Los Zetas, a Drug Trafficking Organization (DTO), have collaborated in a criminal enterprise in those countries and now domestically back in the United States.

Conflict, including the threat or fear of potential violence, or being witness to or a victim of physical violence, constantly surrounds gangs and their communities and is the principal driver sustaining gang life. This Special Issue examines the diverse nature of gang-related violence with the goal of better understanding the growing complexities of gang violence over the last two decades to better inform public policy solutions. The contributions included in this Special Issue highlight the complex nature of gang-related violence in the 21st Century. As much as policy makers, the media, and even scholars like to simplify gang-related violence, all of the studies included in this Special Issue highlight the nuance and variation that exists.

The perpetual growth of gangs and active recruitment within the state, compounded by the continual influx of criminal illegal aliens crossing the Texas-Mexico border, threatens the security of not only Texans, but also all US citizens. Furthermore, the established alliances between Texas prison gangs and various drug trafficking organizations pose a significant threat to the state of Texas and the nation. Gangs now have access to a larger supply of narcotics, which will undoubtedly increase their influence over and presence in the drug trade, as well as increase the level of gang-related violence associated with illegal narcotics trafficking. Illegal alien smuggling has also become profitable for Texas prison gangs and other street gangs, and potentially may pose a major threat to national security. Multi-agency collaboration and networking—supplemented with modern technology, analytical resources, and gang intervention and prevention programs—will be critical in the ongoing efforts to curtail the violence associated with the numerous gangs now thriving in Texas.
