This is the report of the Commission on Law Enforcement and Administration of Justice, created by President Johnson in 1965. This report is about crime in America - about those who commit it, about those who are its victims, and about what can be done to reduce it. Many Americans take comfort in the view that crime is the vice of a handful of people. This view is inaccurate. In the United States today, one boy in six is referred to the juvenile court. A Commission survey shows that in 1965 more than two million Americans were received in prisons or juvenile training schools, or placed on probation. Another Commission study suggests that about 40 percent of all male children now living in the United States will be arrested for a nontraffic offense during their lives. An independent survey of 1,700 persons found that 91 percent of the sample admitted they had committed acts for which they might have received jail or prison sentences. Many Americans also think of crime as a very narrow range of behavior. It is not. An enormous variety of acts make up the "crime problem." Crime is not just a tough teenager snatching a lady's purse. It is a professional thief stealing cars "on order." It is a well-heeled loan shark taking over a previously legitimate business for organized crime. It is a polite young man who suddenly and inexplicably murders his family. It is a corporation executive conspiring with competitors to keep prices high. No single formula, no single theory, no single generalization can explain the vast range of behavior called crime.
