Research Summary

This evaluation of a directed police patrol project utilizes a pre-post quasi-experimental design with a non-equivalent control group as well as an interrupted time series analysis. The results suggest that directed patrol had an impact on firearms crime in one of the target areas but not the other.

Policy Implications

The results suggest that a specific deterrence strategy whereby the police utilize directed patrol to focus on suspicious activities and locations reduced violent gun crime. In contrast, a general deterrence strategy focused on maximizing vehicle stops did not have an apparent effect.
