Decent Essays

Philadelphia Foot Patrol Experiment compared to the Kansas City Preventative Patrol Experiment conducted in the 1970s, was a major research collaboration between the Philadelphia Police Department (PPD) and researchers at Temple University’s Center for Security and Crime Science involving about 240 police officers on foot beats around some of the city’s most violent corners.
Since the Newark Foot Patrol Experiment, it had long been the opinion of many police and criminology researchers that police foot patrols improve community perception of the police and reduce the fear of crime, but they don’t prevent actual crime. Results from the Philadelphia Foot Patrol Experiment suggest a more positive view of intelligence-led targeting of foot patrol …show more content…

Violent crime becomes defined as homicide, aggravated assault, and robberies not occurring indoors, and events became weighted by year. In this way, more recent developments had greater relevance in the creation of the target locations for 2009, but summary values retained a portion of the long-term hotspot component. Two PPD Regional Operations Commanders identified 129 potential foot beats, and from these, 120 became selected for the experiment. Each area contained about 15 street intersections and 1.3 miles of roads. The foot beats were ranked by the weighted volume of violent crime and paired with a foot beat of a similar crime rate. One from each pair was randomly selected to be a target beat, while the other became a control (or comparison) area. There were 60 treatment areas and 60 control areas.
Officers patrolled in pairs with two teams assigned to each foot patrol. 240 officers worked 60-foot beat areas for three months. They worked from Tuesday morning to Saturday night in two shifts (10 am to 6 pm, 6 pm to 2 am). Some officers engaged in community-oriented work, speaking to community members and visiting child care centers and juvenile hangouts, while others were more crime oriented, stopping vehicles and conducting field interviews of
