Psychological Disorders Case Study: Not Guilty by Reason of Insanity The majority of people with serious psychological disorders are not dangerous to others. Some, however, commit violent crimes. Of these, some are found not guilty by reason of insanity and are sent to psychiatric institutions instead of prison. When an accused person pleads insanity, the prosecutor tries to prove that the person was sane at the time of the crime and the defense tries to prove he or she was not. Under law, one must be either all or nothing, but in reality most psychological disorders are a matter of degree. Original Content Copyright by HOLT Mc. Dougal.
