Which policing experiment examined the ability of patrol efforts to control crime and changed our understanding of policing?

The Kansas City Preventive Patrol Experiment, conducted in the early 1970s, examined the impact of different levels of police patrol on crime rates. It found that increasing or decreasing patrol had little effect on crime, citizen fear, or satisfaction with police services. This groundbreaking study shifted the focus of policing from traditional deterrence through visible patrol to more proactive and community-oriented approaches. It highlighted the importance of understanding the role of police in crime prevention beyond mere visibility.
