The researchers conducted the experiment by dividing Kansas City into three areas: a high-patrol area, a medium-patrol area, and a low-patrol area. They then randomly assigned police patrols to each area. The researchers found that there was no significant difference in crime rates between the three areas. This finding suggests that increasing the number of police patrols does not reduce crime rates.
In addition, the researchers found that the high-patrol area had the highest crime rate. This finding is likely due to the fact that the high-patrol area was also the most densely populated area. This suggests that crime rates are higher in areas with more people, regardless of the number of police patrols.
The Kansas City Preventive Patrol Experiment has had a significant impact on police policy. It has led many police departments to reduce the number of police patrols and to focus on other crime-prevention strategies, such as community policing.
