State law requires that neighbors be told, when certain sex offenders are released back into a community. There is often worry amoung residents, who fear the convict will reoffend. Later today, at a national conference of probation and parole officers in St.Paul, there will be some research presented on whether treatment for sex offenders really works. One of the presenters is Robin Goldman, a psychologist and sex offender treatment program director at the state corrections facility at Lino Lakes. She says psychologists have made great progress in treatment approaches in recent years.
