Implementing and evaluating crime prevention and control programs and policies

The history of crime prevention and control efforts in the United States has demonstrated little progressive improvement in our ability to deter crime. The major obstacles to implementing effective interventions and policies have been a weak scientific knowledge base about how to prevent crime, the research community's inability to effectively disseminate what is known about the causes of crime and to translate this knowledge into operational programs and policies, and a resistance on the part of practitioners and policy makers to evaluate programs and policies and to use this information in the development of new programs and policies. In the last decade, there have been major advances in our understanding about the causes of crime and we have now demonstrated the effectiveness of selected prevention programs. But there is little evidence that this scientific knowledge is informing current practice or policy. Problems in the dissemination of this information and the resistance to utilizing it remain. These problems are discussed and suggestions are made for addressing them. Our knowledge base remains modest, but it is now sufficient to inform policy and practice. The research community must work to do a better job of disseminating this information and overcoming the resistance to utilizing it before we will be successful in implementing effective crime prevention programs and policies.
