Four major crime prevention strategies are identified and described: law enforcement, developmental, community, and situational approaches. A prevention framework is presented that encompasses a much fuller range of initiatives than governments typically pursue. Law enforcement or criminal justice crime prevention operates directly through deterrence, incapacitation, and rehabilitation and indirectly through effects on socialization. Developmental strategies aim to prevent the criminal potential in individuals by targeting risk and protective factors; community strategies incorporate interventions to change social conditions that influence offending in residential communities; and situational strategies are intended to prevent the occurrence of crime, especially by reducing opportunity and increasing risk. Key practical and theoretical issues in crime prevention are examined, along with issues relevant to crime prevention measurement and evaluation. 54 references
