Përmbledhja	Situational crime prevention (SCP) is a framework, developed by Ronald Clarke, for reducing crime by changing the immediate situations in which it occurs rather than the dispositions of offenders. It diagnoses the specific opportunities that make a crime easy, rewarding, or low-risk and then applies twenty-five practical techniques organized under five mechanisms: increase effort, increase risk, reduce rewards, reduce provocations, and remove excuses.	Displacement and diffusion analysis evaluates what happens around a crime-prevention intervention: does crime simply move to nearby areas, times, or targets (displacement), or do the benefits spill over so that crime also falls in surrounding untreated areas (diffusion of benefits)? Bowers and Johnson's weighted displacement quotient (WDQ) provides a simple, widely used metric that compares pre/post crime change in a target area, a surrounding buffer, and a control area.
