ABOUT HALF OF ALL OFFENDERS RELEASED ON PROBATION OR PAROLE AT THE FIVE PROBATION DISTRICTS REVIEWED (CALIFORNIA CENTRAL; GEORGIA NORTHERN; ILLINOIS NORTHERN; WASHINGTON, D.C.; AND WASHINGTON WESTERN) HAD THEIR PROBATION OR PAROLE REVOKED, ABSCONDED, WERE CONVICTED OF NEW CRIMES, OR WERE AWAITING TRIAL. OFFENDERS WERE NEITHER BEING CONTACTED FREQUENTLY BY PROBATION OFFICERS NOR RECEIVING NEEDED REHABILITATION TREATMENT. THE ADMINISTRATIVE OFFICE OF THE U.S. COURTS HAS NOT ADEQUATELY MANAGED OR MONITORED PROBATION ACTIVITIES. TO IMPROVE THE SYSTEM, MORE EMPHASIS SHOULD BE PLACED ON SUPERVISING AND REHABILITATING OFFENDERS, AND DISTRICT PROBATION OFFICES SHOULD BE MORE EFFICIENTLY MONITORED AND EVALUATED.
