Defendant convicted of deviate sexual assault; then examined by 2 psychiatrists who said he was a sexually dangerous person. He appealed on 5th Amendment, said psychiatrist took data which incriminated him. Court said this was "civil" action, that just because he would be locked up for life in Maximum Security Forensic Hospital, it was for treatment for his own good, 5th Amendment didn't count. see SPECHT v. PATTERSON for reasonable discussion. 5-4 decision, hotly contested, and should be.
