Every sex offender on active parole has GPS monitoring as part of their supervision requirements. Any sex offender parolee who entered the fair zone set off an alarm notifying parole agents of their whereabouts. Once a notification was received, on-site CDCR parole agents tracked an offender's movement and investigated if any law, parole violation or any public safety issue existed. During the various runs of the fairs, CDCR parole agents received numerous zone alerts, which culminated in parolee arrests for violations of special conditions of parole.
"When it comes to the supervision of sex offenders, we cannot and will not compromise public safety," said Marvin Speed, District Parole Administrator. "Operation Eagle Eye was so beneficial to enhancing public safety that we will replicate the operation at other venues."
