The Plea of Insanity Insanity A legal term, not a psychological or psychiatric one, referring to a person who is unable, because of a mental disorder or defect, to confirm his or her behavior to the law.

10 Jeffrey Dahmer Dahmer was convicted of the murder of 15 young men, whose mutilated, cannibalized bodies had been found in his Milwaukee apartment. At trial, he admitted the killings, but pled not guilty by reason of insanity. His plea was rejected, and the jury found Dahmer to be legally sane at the time of the murders. He was sentenced to 15 life terms. The Dahmer conviction was hailed by many as the death of the insanity defense. If such a clearly deranged killer could not be found legally insane, it seemed unlikely that the defense would ever be successful, at least in a high profile case involving a violent crime.
