The 80/20 Rule in policing, also known as the Pareto Principle, suggests that roughly 80% of crime or calls for service come from 20% of the causes, often concentrated in specific people, places (like high-risk locations), or things, allowing police to focus limited resources for maximum impact on crime prevention and reduction. It's a framework for problem-oriented policing, identifying "hot spots" or high-rate offenders to tackle the core of a problem efficiently, rather than treating every incident equally.
What is the 80-20 rule in law enforcement?
