This report draws on more than a half-century of gang program evaluations to summarize what we have learned about: * Prevention programs (including early childhood, school-based, and afterschool initiatives) * Intervention programs (including those that work to create violence-free zones, establish gang summits and truces, and rehabilitate gang members in juvenile detention and correctional facilities). * Suppression programs (including those focused on prosecution, police response, and geomapping and other tracking systems). * Strategies using multiple techniques (such as community policing). * Multiagency initiatives (including local, State, and Federal efforts). * Comprehensive approaches to gang problems (such as the Comprehensive Community-Wide Approach to Gang Prevention, Intervention, and Suppression). * Legislation (at the local, State, and Federal levels)
