The Bureau of Prisons (BOP) Location Monitoring program stands out as an excellent example of applying the risk principle in the federal criminal justice system. By moving minimum-security inmates from BOP prison camps back into their communities to complete the final portion of their sentence--while on location monitoring and supervised by U.S. probation officers--the BOP and the federal courts are reducing expenditures, reducing low-risk inmates' exposure to higher-risk offenders, and opening up more space in Residential Reentry Centers (RRCs) for higher risk inmates and noncompliant offenders who require much greater programming.
