After an exhaustive search strategy that identified more than 5,500 articles and reports, we found only ten methodologically rigor- ous evaluations that met our inclusion criteria. Using meta-analytic techniques, we found an overall modest but statistically significant impact of POP on crime and disorder. We also report on our analysis of pre/post comparison studies.

Policy Implications POP has been adopted widely across police agencies and has been identified as effective by many policing scholars. Our study supports the overall commitment of police to POP but suggests that we should not necessarily expect large crime and disorder control benefits from this approach.
