The GPS tracking devices do not keep sex offenders from reoffending or any other offenders released back into society. This is a false sense of security based on fear and profiteering of manufacturing companies. The statistics show that sex offenders have the lowest recidivism rate of any other crime besides murder. If a sex offender repeat their crime lock them up for life period. The GPS should be abolished and is in violation under the 4th amendment to the U S Constitution.
