A new report says the California law mandating GPS monitoring of sex offenders can provide a false sense of security for the public.
While it can help law enforcement authorities find suspects after crimes, it has only limited benefits in preventing them.
The report from the inspector general in the state corrections department was released Wednesday. It was requested by the former state Senate leader after two Orange County sex offenders who were required to wear GPS devices were arrested last spring in the rapes and killings of four women.
Both had their whereabouts constantly tracked by satellite.
Monitoring the movements of ex-felons using GPS ankle bracelets is required under Jessica's Law, an initiative passed by voters in 2006. The report found little evidence that it significantly deterred crime.
