The Kansas City patrol experiment tested several patrol styles. Which of the following were included?

• A. Random patrol only
• B. Normal patrol, proactive patrol, and reactive patrol
• C. Visible patrol and undercover patrol only
• D. Daytime patrol only

Answer: (B)

The main idea is how preventive patrol was varied to see its impact on crime and police effectiveness. In the Kansas City Preventive Patrol Experiment, beats were assigned to three patrol levels: reactive patrol (responding to calls only, with no routine patrols), normal patrol (the standard level of patrol before the study), and proactive patrol (increased, visible, random patrols aimed at deterring crime). This design directly tested whether different patrol styles changed crime, arrests, or citizen perceptions. It wasn’t about daytime-only patrols, undercover patrols, or a single, alternate configuration, so the three included styles are the ones described.
