Objectives

We explore whether the use of foot patrol, problem-oriented policing and offender-focused policing at violent crime hot spots negatively impacted the community’s perceptions of crime and disorder, perceived safety, satisfaction with police and their perceptions of procedural justice.

Methods

We report on a repeated cross-sectional survey that was mailed before and after the deployment of concentrated police interventions in 60 small areas of Philadelphia, PA, as part of the Philadelphia Policing Tactics Experiment. Eighty-one violent crime hot spots were randomly allocated to one of three treatments (20 each), or to a control assignment (21). Impacts on the community via seven scales were analyzed using OLS models with orthogonal contrast-coded treatment variables and demographic covariates.

Results

The OLS models estimating changes in the community’s opinions from pre- to post-intervention uncovered no statistically significant changes on any of the dependent variables relative to control locations, irrespective of the treatment type. Even though one experimental treatment condition (offender-focused) reported statistically significant violent crime reductions, the police activity that generated the crime reduction did not noticeably change community perceptions of crime and disorder, perceived safety, satisfaction with police or procedural justice.

Conclusions

As implemented in Philadelphia, none of the policing tactics had measurable changes in resident perception within the communities that were targeted. The results do not support the suggestion that hot spots policing negatively impacts the community. At the same time, no positive benefits were generated.
