Not Guilty by Reason of Insanity (NGRI)
Less than 1 in 500 defendants enter a plea of NGRI, and over 90% of defendants that do enter this plea are found guilty. When a defendant is found NGRI they are not released back into society. Rather, he or she is sent to a specialised forensic hospital for a designated period of time. Depending on the offence, this can actually be longer than the sentence would have been if the person was found guilty and incarcerated. As with competency, being unable to understand the nature and consequences of the offence is not an easy threshold to reach. The defendant must be unduly impaired. In most cases these individuals are so out of contact with reality that they were not aware that they had committed a crime or that what they were doing was wrong. Those found NGRI, for this reason, usually have extensive histories of mental illness.
