Strategies to enhance prosecution of gang-related crimes are presented, with a focus on enforcement and prosecution targeting urban street gangs. The model programs introduced offer strategies largely based on the practical experiences of agencies that participated in a demonstration program, the Urban Street Gang Drug Trafficking Enforcement Program, designed to establish model approaches to prevention and suppression of gang violence. The monograph offers a step-by-step guide to designing and implementing a program based on strategies from the seven demonstration sites. The following chapters guide program implementation: (1) "Introduction"; (2) "Key Elements of the Gang Suppression Prototype"; (3) "Planning and Analysis"; (4) "Gang Information and Intelligence Systems"; (5)"Gang Suppression Operations and Tactics"; (6) "Interagency Cooperation and Collaboration"; (7) "Legal Issues"; and (8) "Evaluation." Appendixes contain an annotated bibliography and sources for further information. (Contains 85 endnotes and 65 references.) (SLD)
