That original report dispelled the popular notion that gang violence was no longer a problem in this country. Based on findings from 26 U.S. cities and metropolitan counties, including interviews with over 450 representatives of police departments, public and private youth service agencies, courts, and other groups, the author found that, compared to youth gangs from previous eras, the gangs of the 1970's tended to be more violent, more likely to use guns, less formally organized, and more active within the public schools. The original research provided baseline national estimates of the numbers, locations, and criminal activities of juvenile and youth gangs, and conceptualized the law-violating youth group as a basic unit in the study of gangs and other forms of collective youth crime. The predictions made in the report have been borne out in the intervening years by empirical data: that absent a new commitment to gang control, the youth gang problem would worsen; that the gang situation in California represents the wave of the future for the rest of the U.S.; that social and economic conditions associated with gangs will not change in a direction that reduces gang crime; and that gun control efforts will be ineffective in decreasing the availability of weapons to youth. 3 charts, 33 tables, and 5 appendixes

Despite the significant contributions from location-based gang studies, the network structure of gangs beyond localized settings remains a neglected but important area of research to better understand the national security implications of gang interconnectivity. The purpose of this dissertation is to examine the network structure of gangs at the macro- and micro-level using social network analysis. At the macro-level, some gangs have formed national alliances in perpetuity with their goals and objectives. In order to study gangs at the macro-level, this research uses open-source data to construct an adjacency matrix of gang alliances and rivalries to map the relationships between gangs and analyze their network centrality across multiple metrics. The results suggest that native gangs are highly influential when compared to immigrant gangs. Some immigrant gangs, however, derive influence by “bridging” the gap between rival gangs. Mexican Drug Trafficking Organizations (MDTOs) play a similar role and feature prominently in the gang network. Moreover, removing MDTOs changes the network structure in favor of ideologically-motivated gangs over profit-oriented gangs. Critics deride macro-level approaches to studying gangs for their lack of national cohesion. In response, this research includes a micro-level analysis of gang member connections by mining Twitter data to analyze the geospatial distribution of gang members and, by proxy, gangs, using an exponential random graph model (ERGM) to test location homophily and better understand the extent to which gang members are localized. The findings show a positive correlation between location and shared gang member connections which is conceptually consistent with the proximity principle. According to the proximity principle, interpersonal relationships are more likely to occur in localized geographic spaces. However, gang member connections appear to be more diffuse than is captured in current location-based gang studies. This dissertation demonstrates that macro- and micro-level gang networks exist in unbounded geographic spaces where the interconnectivity of gangs transpose local issues onto the national security consciousness which challenges law and order, weakens institutions, and negatively impacts the structural integrity of the state.

The youth culture is on everyone's lips today, as pressures build to ban controversial song lyrics, reintroduce school prayer, and prohibit teenagers' access to contraceptives. It's not the first time Americans have been outraged over the seuction of the innocent.. When James Dean and Marlon Brando donned their motorcycle jackets and adopted alienated poses in Rebel Without a Cause, East of Eden, and The Wild One, in the 1950's, so did countless numbers of American teenagers. Or so it seemed to their parents. American teenagers were looking and acting like juvenile delinquents. By mid-decade, the nation had reached a pitch of near obsession with the harmful effects of film, radio, comic books, and television on American youth.

This volume about juvenile delinquency in the United States and United Kingdom includes a foreword, nine chapters organized in three parts, and an afterword. Chapters 1 and 2 in Part I describe juvenile delinquency in both countries and the urgency of the current crisis. Chapters 3 to 6 in Part II deal with the two nations' juvenile justice systems, focusing on structural and ideological obstacles preventing reform. Presented in the final chapters in Part III are suggestions for reform in school, and juvenile justice settings that recognize the importance of character in causing delinquency.
