From Corrections Community, NIC’s great resource blog:
The Center for Evidence-Based Corrections, at the University of California, Irvine, has just posted the results of the first analysis of implementation and outcomes for GPS monitoring of high risk sex offender parolees in California. In Implementation and Early Outcomes for the San Diego High Risk Sex Offender (HRSO) GPS Pilot Program, the authors report on issues encountered with equipment, data use guidelines, effect on parolee recidivism, etc., useful findings as the pilot is in the process of expanding statewide.
Lots of good stuff in the report, far more than I can report on. It's got a description of the problems that come when implementing programs that any program implementer will just nod his/her head at and every non-implementer should be forced to read and take a test on. Just a couple of points to note: the importance of getting offender cooperation with the GPS and the strategies officers have to employ to get that coop, the inevitable involvement and possible abuse of a GPS program by law enforcement, the range of offenses these offenders commit and not just the offenses for which they got labeled a sex offender (when actually they're multi-talented at offenses), and the validity of STATIC-99 as a recidivism predictor for sex offenders but more so for lower risk than higher risk offenders. The key point to take home is probably that, despite concerns, GPS offenders were less likely to abscond than non-GPS offenders, but you may disagree. Read it and let me know, please.
