The major theme of this book is that citizens are responsible for applying their own intelligence, time, and abilities to devise ways to prevent crimes against themselves and their neighbors. The two case studies illustrate how potential crime victims can take relatively simple action that will reduce their probability of victimization. One case study involves the robbery-prevention measures undertaken by 7-11 convenience stores; the other portrays how one Detroit neighborhood reduced its crime rate by 57 percent. General profiles of criminals and their victims are followed by specific instructions on how to prevent street assault, mugging, and rape; burglary; and other forms of theft. How to act when confronted by an imminent victimization is also discussed for particular offenses. A chapter is devoted to crime prevention through community self-help. Recognizing that a high percentage of violent crimes occurs within families, the author discusses when and how to intervene in family disputes to prevent serious harm. The final chapter develops the argument that neither gun possession nor gun control does much to prevent crime, compared to secondary crime prevention such as target hardening.
