A Randomized Controlled Trial Of Different Policing Strategies At Hot Spots Of Violent Crime
Taylor, Koper, And Woods (2011)
Researchers randomly assigned 83 hotspots in Jacksonville, Florida, to receive either a problem-oriented policing (POP) strategy, directed-saturation patrol, or a control condition for 90 days. The POP hot spots had officers using a policing strategy that involved the identification and analysis of specific crime and disorder problems in these spots, in order to develop effective response strategies in conjunction with ongoing assessments.
1) POP Strategy: Small officer teams working with an crime analyst explored the "root cause" of the violence problem in the hot spot and came up with ways of solving it using an environmental crime prevention technique, or a well-tested approach from the Office of Community Oriented Policing Service POP guides. 2) Directed Saturation patrols: provided with additional focused/precision policing to create a heightened police presence in specific locations with high concentrations of violent crime. 3) Control hot spots were provided with standard policing efforts involving traditional patrol operations, without the introduction of any additional resources.
1) The use of POP was associated with a 33% reduction in the count of street violence during the 90-day post-period. 2) Also, while not statistically significant, they observed that our POP group was associated with other non-trivial reductions in violence and property crime. 3) There were no statistically significant crime reductions for the saturation/directed patrol group, though crime levels were lower for this group during the intervention period itself.
