This is an introduction to crime prevention through environmental design (CPTED), which is the "proper design and effective use of the built environment that can lead to a reduction in the fear and incidence of crime, and an improvement in the quality of life." CPTED encompasses (1) the criminal offender perspective regarding an environment and the risk of getting caught when committing a crime and (2) the social dynamics, sense of ownership of the environment, and their associated protective actions by persons who work, live, or traverse the environment en route to another destination.
