Directed patrols reduce gun violence


Gun violence is a serious and pressing crime problem throughout the world. A variety of law enforcement strategies have been explored in an attempt to reduce the criminal misuse of firearms.

 

The findings from a recent Campbell systematic review suggest that the strategy of directed patrols, focussed on illegal gun carrying in high-crime areas, prevents gun crimes.

 

The review team, led by Christopher S. Koper, examined 7 non-randomized tests of directed patrols in three American cities and two Colombian cities. The Colombian studies revealed a 10% to 15% reduction in firearm homicides, while the American studies (with one exception) revealed a reduction in gun-related crime by 29%-71%.
