WASHINGTON, May 10, 2012 — The United States Department of Justice’s National Institute of Justice (NIJ) recently released a study that evaluated the use of global positioning systems (GPS) technology to monitor high-risk sex offenders on parole in California.
Offenders in the GPS group demonstrated significantly better outcomes than offenders who were monitored in traditional ways. The evaluation showed that risk for a sex-related violation was nearly three times greater for offenders who received traditional parole supervision, than offenders who received GPS supervision. The risk of committing an offense that resulted in an arrest was twice as high for offenders who received traditional parole supervision than for offenders in the GPS group.
When compared to traditional supervision, the study found that GPS monitoring costs approximately $8.51 more per day. The outcomes of GPS monitoring, however, are significantly better.
