Hot spots policing and directed patrols are similar strategies which focus on increasing law enforcement resources in areas known to experience high rates of crime. Directed patrols targeting gun violence typically include intensive patrol in high gun crime areas. Directed patrols are usually larger than hot spots. With both strategies, officers focus on proactive enforcement and investigation rather than responding to calls for service. Officers assigned to each priority area will diagnose the root causes of crime and disorder and address them, creating a crime prevention-based system.
