I'm not sure I understand this.  And if there are any defense attorneys out there that can help, feel free.  A person who is mentally deranged who neither appreciates what a murder is or what it means is somehow still culpable by virtue of treatment and medication that make the defendant eligible to responsibly participate in his defense at trial.  He's not the same defendant that killed the victims.  Mental state is everything.  It sounds scurrilous to me.  Not Guilty by reason of insanity should get him intense supervision and proper treatment including proper medications.  Revenge is not thicker than psycho-biological disorders.
