A recent audit of Tennessee’s parole and probation system found officers failed to properly supervise sex offenders, sometimes allowing them access to children. The Tennessean reports the state monitors about 800 felons by GPS. Most of them are sex offenders. However, auditors found that parole and probation officers were ignoring many of the alerts they received when sex offenders enter a prohibited area, such as a school zone. Only about 18 percent of the alerts were checked out. Auditors also found that officers missed home visits in nearly 40 percent of the cases they audited. They didn’t make sex offenders get drug tests in almost half of the cases, and they failed to make sure sex offenders were going to treatment in 40 percent of the cases.
