An interesting report from the Brookings Institution:
Two-thirds of those released from prison are re-arrested within three years. This incarceration cycle hurts families and communities—and also costs a lot of money. Governments and nonprofits have tried many programs to reduce recidivism, but most are not successful. In a recent review of the literature on prisoner reentry, I summarized the best evidence on how to improve the lives of the formerly incarcerated. One of the most striking findings was that the intensity of community supervision for those on probation or parole is a highly cost-effective strategy. Several studies of excellent quality and using a variety of interventions and methods all found that we could maintain public safety and possibly even improve it with supervision—that is, fewer rules about how individuals must spend their time and less enforcement of those rules. Less supervision is less expensive, so we could achieve the same or better outcomes for less money.
