Five case studies of well-planned and well-executed community crime prevention programs are presented. The first was initiated by the Royal Canadian Mounted Police (RCMP) detachments serving Portage la Prairie and its adjacent rural areas, the second by a professional health association in British Columbia, the third by the management of a chain of convenience stores, the fourth by a municipal government, and the fifth by the crime prevention unit of a large city police department. The four components of successful crime prevention models are examined: problem definition, program planning and development, implementation, and evaluation. The handbook suggests several methods for involving the community in the crime prevention program, including conducting a community survey; carrying out systematic interviews with criminal justice officials and people who are familiar with the community and local issues; holding group meetings of community members; and organizing public hearings, commissions, and task forces. In addition, information should be obtained about the physical and social characteristics of the community and its residents. The appendixes provide a sample questionnaire for members of the community and assess various crime prevention approaches, including media campaigns and property marking programs. Five figures and a 68-item bibliography are included.
