The examples illustrate six elements that are necessary in any crime prevention program: structure, leadership, information, identity, durability, and resources. Structure should provide leadership and organizational support for crime prevention, gather information to assist in identifying crime problems, formulate local plans for crime prevention, and draw together organizations and individuals with the experience and skills needed to implement preventive measures. The cooperation of organizations in crime prevention requires one individual or agency to take a leadership role. Effective crime prevention activities should be based on accurate information, and such information can be obtained from police statistics, public surveys, and victim and offender interviews. Crime prevention projects should emphasize the special and distinctive nature of the project and assure visibility through structure, media support, appropriate logos and designs, and community involvement. Twenty-seven successful crime prevention schemes in England are described. A report annex cites a program known as Crime Concern that was initiated in 1988 to stimulate, support, and develop local crime prevention programs.
