This document summarizes different approaches to crime control, prevention, and punishment. It discusses right and left realist perspectives on reducing crime through increasing costs and focusing on individuals versus addressing societal inequalities. It also examines situational crime prevention techniques like surveillance and environmental crime prevention approaches like fixing signs of disorder. Left realists argue for addressing root causes of crime like poverty. The document evaluates different rationales for punishment and whether prisons are effective in deterring crime or act as "universities of crime" that fail to rehabilitate and reduce recidivism.
