Supreme Court Ruling on Sex Offenders

NPR's Nina Totenberg reports on today's decision by the Supreme Court on when a sex offender who has finished his prison term can be committed to a mental hospital. The justices ruled 7-2 that states must offer proof of that the individual has serious difficulty in controlling behavior. The dissenting justices, Scalia and Thomas, said the ruling didn't give courts enough guidance on how the lack of self control should be determined.
