The first phase of the demonstration program in each city was to integrate crime and drug prevention activities into all law enforcement operations. In phase two, each police agency developed working partnerships with its city's other government agencies, community groups, religious institutions, and schools. In phase three, the programs increased their activities and expanded into new neighborhoods. In both efforts, crime prevention was declared an emphasis of the entire police department and thus a part of rather than a separate activity from patrol and investigation. These successful programs used the systems approach and offer ideas for other jurisdictions interested developing programs that effectively combine crime prevention and community partnership concepts.
