Incorporating a quasi-experimental design, this study evaluated a saturation foot-patrol initiative in Newark, New Jersey within a target area, a surrounding catchment area and two separate control areas. Violent crimewas measured one year before the experiment and during the initiative. The authors found that foot-patrol can serve as an effective crime prevention tactic as street violence, murder, shootings and nondomestic aggravated assault decreased within the target area. The study also found that during the saturation foot-patrol initiative, robbery suffered from substantial levels of temporal and spatial displacement, having varying impact on different types of street violence. The authors suggest that police should design large-scale foot-patrol efforts in ways that do not allow offenders to notice the intervention and identify alternate crime opportunities.
