This timely revision provides an up-to-date collection of the research on crime prevention. The prevailing approaches and strategies are organized into categories of primary prevention (designed to prevent conditions that foster deviance), secondary prevention (directed toward persons or conditions with a high potential for deviance), and tertiary prevention (dealing with those who have already committed offenses). The effects of physical environments, the mass media, displacement and diffusion, electronic monitoring, and home confinement are also explored. In addition to presenting a discussion of the different prevention approaches, the author provides insight into the effectiveness of each approach. Features: a new chapter on developmental crime prevention focuses on the early life experiences that predispose individuals to commit deviant acts and using risk factors in predicting behaviour for secondary prevention; new attention is brought to situational prevention, partnerships for crime prevention, the politics of prevention strategies, and the tangential topic of organizing dysfunctional neighbourhoods; and all chapters now include updated tables that indicate the state of the evidence as well as key terms, learning objectives, web references, and a helpful glossary.
