the criminal justice system to solve its crime problem. With the 1990s upon us, what can we say about the success of crime control policies that rely on the criminal justice system? The picture, taken one approach or program at a time, is not good. It is now generally agreed that the criminal justice system fails to rehabilitate offenders, to make them less likely to commit criminal acts as a result of treatment or training; that the system fails to deter potential offenders, to make them less likely to commit criminal acts out of fear of penal sanctions; and that such programs as increased police patrols, reinstatement of the death penalty, and modification of the exclusionary rule are unlikely to have much effect on crime, at least within the limits imposed on them by reasonable assessments of their costs.
