In addition, REACT investigates and presents for criminal filing cases of sex offenders who fail to comply with registration requirements. REACT units also obtain information on sex offenders that often proves useful for other law enforcement entities. REACT compiles information on offenders' past crimes and modus operandi, thereby providing sexual assault detectives valuable leads in solving current sex crimes; REACT records and investigates notifications of offenders moving into the Los Angeles area; and it notifies other law enforcement agencies when local offenders move to their areas and provides information on those offenders' criminal histories. Further, it responds to citizen notifications of offenders not complying with registration requirements, which assures the public that the department continually monitors registered sex offenders within its boundaries, thereby reducing the fear of crime. Increased monitoring of sex offenders fosters greater cooperation between law enforcement and other criminal justice agencies charged with supervising these individuals during probationary or parole terms. REACT also works closely with its counterpart in the California Department of Justice, the Sexual Predator Apprehension Team. This team accompanies REACT units in periodic field compliance checks of the addresses of registered sex offenders. 8 notes
