This document discusses crime analysis and its applications in community-oriented policing. Crime analysis involves understanding crime patterns through statistical analysis and crime mapping to identify problems and potential solutions. It helps police departments target areas with high crime rates or unusual increases in crime. Crime analysis also examines relationships between crimes in terms of time, location, offender characteristics, and causal factors to aid investigations of serial crimes and displacement. The core functions of law enforcement like prevention, investigation, and apprehension can be enhanced through crime analysis.
