Mara Salvatrucha, or MS13, is one of the world’s largest and most violent street gangs. It is also one of the least understood, making it difficult for policymakers and law enforcement to confront. A new report by InSight Crime and American University’s Center for Latin American & Latino Studies (CLALS) reveals new details about the gang’s operations and provides policy prescriptions for eradicating MS13. Entitled “MS13 in the Americas: How the World’s Most Notorious Street Gang Defies Logic, Resists Destruction,” the report is based on hundreds of interviews with, and surveys of gang members and law enforcement officials in El Salvador, Washington, D.C., Los Angeles, and Long Island. It contains insights into the gang’s hierarchy, politics, structure, and recruitment methods.

The research into children and young people’s experiences of gang-associated sexual exploitation and sexual violence is exploring:

• The scale and nature of the issue in the specific areas of England under study;

• Pathways into gang-associated sexual exploitation and sexual violence for young people living in these gang-affected neighbourhoods; and

• Potential models of response.

The research is being conducted over the two-year period of the OCC Inquiry (Autumn 2011 to Autumn 2013). It has a narrower focus than the Inquiry, considering only those forms of sexual exploitation and sexual violence occurring in or related to gangs, as defined below.1 As the prevalence and nature of such gangs varies significantly across the country, exposure to these issues also varies significantly for young people living in different communities and locales.

The national correspondents prepared reports on SRD surveys in their countries. Then, a three days seminar took place in Paris from 17th to 19th January 2008 and was attended by the promoters of CRIMPREV, most of the national correspondents and the general rapporteur. Seven reports covering twelve countries were presented. The countries included were Belgium, England, Finland, France, Germany, Ireland, Italy, the Netherlands, Northern Ireland, Scotland, Sweden and Wales. The seminar gave the participants the opportunity of presenting and discussing the reports. Then the general rapporteur prepared an intermediate report of the situation and asked the national correspondents to introduce minor modifications to their papers according to the discussions that took place during the seminar. The final versions of the national reports were then handed over to the general rapporteur who established a first version of this final report that was discussed with the promoters of CRIMPREV in a meeting that took place in Bologna on 9 July 2008 and sent for comments to the national correspondents. Accordingly, this report is based on the national reports, the discussions that took place during the Paris seminar and the Bologna meeting, and the comments of the national correspondents, as well as This report is focused on general SRD studies, but surveys conducted in order to measure specific behaviours such as bullying or drug use are also covered. It includes a discussion of definitional issues, a short synthesis of the national reports, a historical overview of the development of SRD studies, a discussion on methodological issues related to that measure of delinquency, as well as an analysis of the impact of SRD surveys on criminological theories and criminal policies.

Getting the principles, procedures and practices of child justice right is essential to preventing crime in South Africa. In this monograph the authors chart the history of child justice in South Africa, and internationally. They describe recent developments in child justice in South Africa, and contextualise the South African approach by reflecting on international standards. This monograph provides details about the new Child Justice Bill. The Child Justice Bill provides an enlightened approach to dealing with young offenders and offers a chance to break the cycle of crime. Included in the new Bill are provisions for diverting child offenders out of the criminal justice system through the possibility of community-based sentencing. The Bill also provides a firm legal basis for restorative justice that attends to the needs both of victims and perpetrators.

This paper isolates the causal effect policing has on group violence. The problem of reverse causality from violence to policing is addressed us-ing a change in the allocation of the Stockholm Supporter Police following the 9/11 terrorist attack in September 2001 and the Tsunami Catastrophe in December 2005. We analyze unique data on supporter violence in Swe-den before, under, and after the period supporter police was reallocated to anti-terrorist activities and to Tsunami-related activities.

Violence and supporters’ behaviour at sports events in the region have been subject to innumerable newspaper articles, TV reports, including several sociological studies. Despite this, public hunger for information about extreme supporters and their behaviour (considered provocative by the public) and numerous explanations of the phenomenon are certainly not definitive. Each new fan incident only further amplifies the interest in this matter and replicates attempts to finally answer numerous intriguing questions raised in this regard. Over the past years, the Republic of Serbia has doubtless faced hooliganism at sports events. This phenomenon is developing both in qualitative and quantitative terms, and will persist in future as well. In addition to poor quality of the game and the visibly lower standard of living, the fact that fan incidents have become much more frequent and serious has also affected the diminished interest in sports and dissuaded many fans from visiting sports arenas. In contrast, it seems at first sight that the crisis of the sports public has affected the least the grandstands reserved for extreme fans. Some young people, who otherwise would not be directly interested in watching matches, consider the behaviour of extreme fan groups attractive and exciting. It is exactly such behaviour that attracts them to sports premises. All this has brought about the formation of an aggressive subculture of violent fan groups and constant provocation of incidents as the arrival at a sports event is not motivated by club support, but by the desire to manifest violence and vent negative emotions. Solving the problem of hooliganism at sports events is not an easy and simple task. Hooliganism at sports events may be reduced to a socially acceptable degree with the implementation of quality security assessments of the risk of incidents, by monitoring extreme fans and pre-empting their intentions, isolating them, performing efficient intervention, and by ensuring coordinated cooperation among government authorities, sports organisations and clubs, educational institutions and the media. In tackling violence at sports events, repressive measures should not be entirely disregarded, on the contrary. However, a proactive police approach and preventive measures should be given priority. Such an approach enables mingling of different, opposing fan groups, and need not result in conflicts and violence. Namely, fans may together support their favourite club and establish good, or at least satisfactory mutual relations.

For the millennial generation, the transition to adulthood has become increasingly heterogeneous. These changes have led to a theory and body of research referred to as emerging adulthood. This period of life is of interest to criminologists because, as the well-known age crime curve indicates, during the early adult years the majority of young people who were engaged in delinquent behaviour as adolescents desist. Using a contemporary sample, this thesis firstly examines whether the concept of emerging adulthood is relevant to Dutch young adults, finding that, broadly speaking, it is. In an examination of the risk factors for delinquent behaviour are during emerging adulthood, parental support is found to protect against delinquency and excessive alcohol drinking is found to increase the risk of delinquency. In the remaining four chapters, the relevance of life-course theories of crime are tested. The evidence indicates that transitions into adult roles remain relevant for desistance from delinquency, but that changes in personality during this period also play a role. ‘Boomeranging’ between roles is found to increase the likelihood that young adults do not desist, and finally, achieving financial independence from parents is found to promote desistance, pointing to the importance of examining ‘new’ adult roles.

We know that most persistent offenders who cause considerable damage to society showed delinquent behavior in childhood. However, the long-term development of childhood arrestees is not well understood as longitudinal data are largely lacking. Dothese high-risk children develop long-term offense patterns? Or are even the youngest children with a police contact capable of growing into law abiding adults? Or is it both? And, in case of the latter, which childhood arrestees stop showing delinquent behavior, and which children persist in crime into early adulthood? By providinginsight into the long-term development of offending of childhood arrestees, and uncovering its explanatory factors, the current thesis improves our understanding of the delinquent development in this high-risk offender group.The current thesis reveals that, in contrast to popular belief, childhood arrestees are not predestined to develop persistent delinquent behavior, as most children are not re-arrested between the age of 12 and 25. Recidivists display heterogeneity in their re-offense patterns, with only a small group of children developing into persistent offenders. Accounting for simultaneous risk exposure across life domains proved necessary to explain why childhood arrestees follow one trajectory over another. Problems in multiple life domains were found to predict persistent offense patterns.

"This book analyses the non-custodial government of young offenders in two major cities in Brazil. In doing so, it delves into the paradox of an institution exerting control over youths while at the same time promoting their autonomy and responsibility. The study sheds light on the specific logics of power, control, and inequality produced by such institutional settings. The book’s analysis is based on an ethnographic study of ‘Assisted Freedom’ (Liberdade Assistida) – a form of probation – in the Brazilian cities of Rio de Janeiro and Belo Horizonte. This particular context – which is characterized by endemic violent crime, on the one hand, and a highly protective juvenile justice system, on the other – sheds productive light on the contradictions of juvenile justice systems and other public policies based on the values of citizenship, autonomy, and responsibilization. The analysis takes the form of an inverted zoom structure: it begins by looking at cognitive and interactional processes at the level of interpersonal relationships between youths and professionals, and then works its way up to examine ties outside the institution itself, with schools, the labour market, and juvenile courts. Written in a clear and direct style, this book will appeal to students and scholars in criminology, sociology, cultural studies, and social theory and those interested in learning about non-custodial measures and the regulation of juvenile delinquency."

Privatization of juvenile facilities and services has been the norm since the inception of the juvenile justice system. However, little research has been performed examining the impact of privatization on juvenile justice, despite the possible repercussions of this policy for the juveniles served. Prior research on privatization in other fields has tended to find a connection between privatization and outcomes; however, very little research has examined how privatization impacts operations, how operations impact recidivism, and how privatization and operations interact to produce juvenile justice outcomes. This exploratory study, informed by cybernetic systems theory and principal-agent theory, examined the mechanism by which privatization influences juvenile recidivism by exploring the possible mediating effect of facility operations. Using annual juvenile facility evaluation and recidivism data collected by the Florida Department of Juvenile Justice through 548 evaluations performed on 158 facilities from 2003-2006, this research examined whether facility operations mediated the relationship between ownership (public, for-profit, and non-profit) and juvenile recidivism. Multilevel analyses were completed using Stata software to account for the clustered nature of the data (facilities nested within provider companies). The results from multilevel regression analyses indicated no relationship between ownership type and either operations or recidivism. However, multilevel regression analyses indicated significant inverse relationships between recidivism and each of four of the operational variables: program management, health care services, security, and intervention management. A mediating relationship was not supported. Results also indicated that both provider company and characteristics of the juveniles served were significant predictors of both operational variables and recidivism. These results suggest that privatization concerns may be more suitably focused on identifying the appropriate provider company rather than on choosing the appropriate ownership type. In addition, during the contract negotiation stage, juvenile justice administrators may wish to incorporate policies and/or incentives into the contract that are related to juvenile characteristics. Recommendations for future research are also discussed.

In recent history, various European countries, such as France, have been the scene of recurring violent youth riots targeting the police. Not all countries have, however, been equally affected by the phenomenon. Some countries, such as Germany, have been spared by such large-scale youth riots. Why do some countries witness greater tensions between young people and the police than others? This book aims to understand this discrepancy by shedding light on how young people perceive, experience and relate to the police. Based on an original data set, it investigates the relationship between young people and the police in four cities in Germany and France that present similar structural characteristics, such as their size and ethno-cultural diversity. The relationship is examined in more detail by means of three aspects: young people’s frequency and type of police encounters, their attitudes toward and their willingness to cooperate with the police. The book addresses two main questions: 1. Across countries, are there any common predictors for positive relations between young people and the police? 2. Within countries, is there evidence for profiling practices targeting ethnic and disadvantaged minority juveniles? Which consequences do experiences with institutional discrimination have on young people’s perceptions of and their propensity to cooperate with the police? The book tests the influence of a variety of predictors on the type and frequency of young people’s encounters with as well as their attitudes toward the police. In addition to ethnicity and gender, the analyses consider the possible influence of social and behavioral variables, such as social status and experiences with delinquency, but also prior encounters with the police and neighborhood deprivation. From a theoretical perspective, the book is mainly based on work examining the preconditions of police legitimacy and the consequences of a lack thereof on the citizens’ willingness to act in abidance with the law. The findings suggest that, overall, in both Germany and France, similar predictors shape the relationships between young people and the police. Social status, religious values and norms, identification with the host society as well as prior experiences with crime and the criminal milieu play important roles. There are, however, striking differences between the two countries, too. In Germany, on average, young people with a migration background are checked by the police about as often as those of German descent. Attitudes toward the police are, with few exceptions, consistently positive across gender, age and ethnic backgrounds. In France, the results indicate systematic discrimination of young people of a North African origin by the police. Compared to young people of French descent, the chance of experiencing a “stop-and-search” police encounter is more than twice as high. Finally, the attitudes of young people of North African origin toward the police are significantly worse than those of other young people in France.

This paper explores the evidence available on the role of work in youth participation in violence, through a study of recent research and evidence in this field. The evidence review considers the role of ‘work’ broadly, seeking to go beyond restricted definitions of waged and formal sector employment or underemployment. It considers the role of formal and informal work, different forms of work, and the various potential roles – both positive and negative – that work may play in youth participation in violence. The study will also employ a broad definition of ‘violence’ – considering youth participation in organised, mass-mobilised conflicts; ‘radicalised’ or ‘extremist’ violent groups; less formal, criminal violence; and, where relevant, interpersonal violence. The deliberately broad definition of violence facilitates a focused analysis of the evidence and research surrounding the role of work in youth engagement in all forms of violence that constitute a disengagement from a peaceful social order, recognising the interlinkages between multiple and varied outward manifestations of violence (for example, criminal, economic, political and interpersonal violence). The study explores the evidence for the role of work in youth violence participation at the intersection of multiple forms of work, multiple forms of violence, and multiple forms of participation, mapping gaps in existing research and evidence, and opportunities for further research and analysis. Attention will be concentrated on research and evidence produced after 2010, building on the work of Cramer (2010) on unemployment and violence.

In Maharashtra, state-sponsored programmes that support school dropouts and young offenders in finding employment and integrating into society are severely limited by a lack of resources and capacity. While several government-sponsored schemes do exist, in reality, however, support for school dropouts is largely provided on an ad hoc basis, and predominantly by non-governmental organisations. In this context, we conducted a mixed-methods evaluation of Kherwadi Social Welfare Association’s Yuva Parivartan programme. This is one of the largest non-governmental interventions directed towards school dropouts and juvenile offenders. The overarching evaluation question adopted was ‘Can targeted preventive action and access to employment for school dropouts act as a preventive measure against delinquency and crime?’ The following five programme-specific Sub-Questions (SQ) were used for evaluation purposes: SQ1: Is the Yuva Parivartan (YP) programme effective at imparting on youth a set of prosocial values that are consistent with job-seeking and crime-avoidance behaviours? SQ2: Are the benefits of the YP programme reaching the population who self-report committing a crime? SQ3: Does the YP programme lead to pro-social behavioural changes? SQ4: Is there a relationship between attitudes towards aggressive and/or violent behaviour, entitlement, anti-social intent and employment outcomes? SQ5: Does the YP programme manage to instill a feeling of confidence among the trainees about their future prospects of finding a job?

Much of Africa is urbanising fast and its young population is projected to constitute the largest labour force in the world. While urbanisation can be linked closely with economic development, we also know that it is the least developed countries that have younger populations than the rest of the world. This duality implies that understanding the nature of risks and vulnerabilities faced by urban youth, how they are impacted by them, as well as how they respond to and may be resilient against them, continue to be important questions for furthering development in sub-Saharan Africa. A key conceptual debate surrounds how the category of ‘youth’ is understood, as several definitions of the term exist, ranging from age bands to social or cultural framings. In this paper we look to review how the various definitions of ‘youth’ relate to three dominant discourses about poverty and vulnerability in urbanising Africa: (1) food insecurity; (2) unemployment/joblessness; and (3) violence/insecurity. By doing so, we seek to identify if and when these are responsive to youth needs and practical in terms of policy efforts aiming to reduce poverty and vulnerability in urban areas.

“This is a book of stories telling of Youth's encounter with the law. It does not pretend to cover any particular phase of child psychology nor is it written with the slightest idea of serving as a manual on juvenile-court work in general. It merely seeks to present, in narrative form, a number of incidents from the records of our Children's Court, and to include only such comments as seem appropriate and necessary to bind these sketches together into one consecutive whole. If this little volume serves, in some slight measure, to stimulate popular interest in the problems of delinquency and neglect, if it leads to a clearer understanding of what can be done to-day to develop and elevate our citizens of to-morrow, and if it helps to suggest a possible improvement in the methods and spirit of modern justice, it will more than achieve the objects for which it has been written. All of these stories are true and all are based upon actual facts and occurrences.”

A Study of the Procedure in Chicago, Boston, Philadelphia and New York. Many persons interested in problems of social hygiene have felt that in the courts dealing with sex offenders serious administrative inequalities often operate against women delinquents. Some learning of the provision for trial by jury of prostitutes in Chicago, believe this to be an important safeguard against sex discriminations. Indeed, at various times it has been publicly proposed that an effort be made in New York City to secure legislation to permit trial by jury in all classes of sex offenses. The American Social Hygiene Association and the Bureau of Social Hygiene have been repeatedly appealed to for their views on this and other points connected with the courts dealing with sex delinquents. They finally decided to undertake jointly a study of the Morals Court of Chicago, with no preconceived findings to be reached and no propaganda to spread.

“The system of penal institutions of any state and the planned of administration of each given institution are determined in part at least by certain conceptions regarding the persons who are handled. These conceptions may be vague and unformulated they may be definite and dogmatically propounded. In either case they form one important element of the determination procedure and become of practical importance The acceptance this point view has become almost universal among those who interest themselves in modern penology from either theoretical or more practical aspects.”
