Drawing upon literature from developmental criminology and place-based policing, the Redlands, California Police Department developed the Risk-Focused Policing at Places (RFPP) approach to preventing and reducing juvenile delinquency. The RFPP program is a community-oriented policing and problem-solving strategy that targets risk and protective factors related to delinquency and problem behaviors of youths living in census block group areas. We used a matched block randomized experimental design to evaluate the effects of the program on youths living in 26 census block groups in Redlands. We find that the RFPP program did not influence self-reported delinquency, or perceptions of risk and protective factors and police legitimacy. We argue that the primary explanation for the absence of a program effect centers on the unit of analysis used for the program. The census block group is too large a geographic unit of analysis to achieve the kind of targeted and focused interventions that lead to positive crime-prevention outcomes.
