From US Dept. of Justice-Prevent Crime in Hot Spot Areas

As the second publication in the Crime Prevention Research Review series, this report summarizes the findings from all rigorous academic studies evaluating police enforcement strategies in hot spot areas. It finds that focusing efforts on places with high crime and calls for service can effectively be used to prevent crime in those locations. Reduced calls for service and other reductions in crime and disorder measures were noted in most studies. Displacement of crime due to the enforcement efforts was not prevalent in those studies that measured displacement.
