Constitutionality Of MN’s Sex Offender Program QuestionedMinnesota senators who met Monday at the Capitol say they must act quickly to modify the state's sex offender treatment program before a federal judge does it for them. The judge has said lawmakers must alter the state's system of keeping sex offenders in indefinite custody after they finish prison terms, or risk a ruling that it's unconstitutional. Former Minnesota Chief Justice Eric Magnuson heads a task force that's working to revise Minnesota's sex offender treatment rules. "The way you are operating, it does not work because nobody gets treated, and nobody gets out,” Magnuson said. “And it is, in effect, a life sentence."
