The supervision and monitoring of sex offenders has been one of the most hotly contested areas in corrections policy in recent years.  The public has called for greater levels of offender scrutiny as the result of heinous acts perpetrated by sex offenders, while critics point to recent legislation with onerous housing restrictions coupled with public censure that prevent many offenders from reentering successfully into society.  The current study provides a test of the effectiveness of GPS monitoring for high risk sex offender parolees over and above surveillance and monitoring provided by specialized sex offender caseloads.  Using data from a GPS pilot program, 94 high risk sex offenders monitored by GPS and 91 high risk sex offenders on specialized caseloads were followed for 12 months.  GPS sex offenders were less likely to be found guilty of failing to register as non-GPS sex offenders and marginally less likely to abscond- reflecting relative success in meeting two goals of sex offender legislation – knowing where sex offenders are and making sure they are registered.  Additionally, GPS offenders were less likely to be found guilty of committing a new criminal violation; however we observed no significant differences in the type of new crime violation.

Global Position Satellite Monitoring for High Risk Sex Offenders in San Diego: Implementation and Outcome Analysis of a Pilot Study

Sex offenders, particularly those classified as “high-risk” to re-offend, represent a substantial danger to public safety upon their release from incarceration. Correctional professionals view this risk as uniquely difficult to address due to the lifelong duration of the offending behavior, the propensity of sex offenders to be highly manipulative and deceitful, and the high percentage of sex offenses that go unreported due to the victim and offender knowing one another. With 8,943 sex offenders under parole supervision at the end of 2004, and 1,906 of those classified as high risk, addressing the danger of sex offenders is a serious community supervision responsibility for the state of California.

The state of California has launched a pilot project to employ GPS monitoring to supplement their supervision of their High Risk Sex Offender (HRSO) parole caseload. The purpose of the project is to reduce victimization by sex offender parolees through enhanced deterrence and detection, and to expedite the solution of crime, particularly sex crimes, by combining the GPS data on sex offender whereabouts with law enforcement data on crime locations. In the pilot, 80 HRSO’s on four parole caseloads in San Diego County will be outfitted with GPS tracking devices. It is the intent of the state to expand the program throughout the state if it proves successful.

The major research questions of the research are: 1) What motivated the GPS HRSO program/what is the program design?2) What are the characteristics of the offenders who participated in the pilot/how do they compare with other HRSO offenders in San Diego and statewide? 3)What were the implementation experiences? 4) What impact did GPS have on system and offender behavior? 5) What were the costs of the pilot program? Both qualitative and quantitative methods will be used to address these questions. HRSO offenders who are currently not under GPS supervision will serve as a comparison group for the study.

Drawing on official data and original interview data on 315 transgender inmates in California prisons for men, this research provides the first empirical portrayal of a prison population in California that is unique by virtue of being both transgender and incarcerated. Situated at the nexus of intersecting marginalities, transgender inmates in California prisons are diverse with regard to their gender presentation, gender identity, sexual orientation, and sexual attractions. In addition, both incarcerated and non-incarcerated transgender populations fare far worse on standard demographic and health measures than their non-transgender counterparts in the U.S. population, the California population, the U.S. prison population, and the California prison population. With the possible exceptions of partnership status and educational attainment, these factors combine to reveal that transgender inmates are marginalized in heretofore undocumented ways. At a time in which evidence-based corrections is increasingly embraced by corrections officials in the U.S., this article provides the first systematic profile of transgender prisoners as a heretofore “forgotten group” of prisoners (Tewksbury & Potter, 2005).
