We know that residency restriction are not make communities safer, and in fact do more harm than good. That point is made abundantly clear in a report from the California Sex Offender Management Board.
CASOMB was responding to a bill that would have authorized California towns and cities to implement such restrictions after they were struck down by the California Supreme Court last year. CASOMB says that’s not such a good idea.
When it comes to residence restrictions and, to a slightly lesser extent, exclusion zones, the research and evidence is sufficiently clear. There is no research which supports the use of these strategies, there is substantial research showing that such policies have no effect on preventing recidivism, and there is growing body of research which indicates that residence restrictions actually increase sex offender recidivism and decrease community safety.
