Crime prevention in the United States emerged in the late 1960s and early 1970s as an effort by police and community members to eliminate both the risks of crime and the causes of crime. Prevention needs to be part of our way of doing business at all levels of government and across all elements of society. This report presents 10 action principles describing quality crime prevention efforts. It outlines what features these programs should have and draws from experience and research to emphasize concepts that run throughout the work of more than 3 decades. The 10 principles include: (1) preventing crime is everyone’s business; (2) preventing crime is more than security; (3) preventing crime is a responsibility of all levels and agencies of government; (4) preventing crime is linked with solving social problems; (5) preventing crime is cost-effective; (6) preventing crime requires a central role in law enforcement; (7) preventing crime requires cooperation and collaboration by all elements of the community; (8) preventing crime requires education; (9) preventing crime requires tailoring to local needs and conditions; and (10) preventing crime requires continual evaluation and improvement. 15 Notes
