defence can be taken by convict

Some accused or guilty persons who are being tried for murder or other type of heinous crime often use the insanity defense which is also known as the NGRI plea means “Not Guilty by Reason of Insanity” so they can get least amount of punishment or can easily escape with it. Defendants claim that they were not legally responsible for their criminal acts because they were not in the right state of mind at the time of crime.
