概要	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.	Deterrence analysis studies how the threat and imposition of legal punishment discourage crime. Rooted in classical criminology and formalized in Gary Becker's economic model, it distinguishes the certainty, severity, and celerity of punishment, separates perceived from objective sanction risk, and uses quasi-experimental and perceptual evidence — synthesized by Daniel Nagin — to test how much, and through what channels, punishment actually deters.
