I saw this yesterday, and thought it was pretty fucked up that they would only get him 'sane enough to understand the Court procedings"...not try and help him get straightened out so he isn't a danger to Society anymore.
If he really is nutty ( which I believe he is nuttier than a fruitcake)...why only help him enough to let him understand he is on trial for something he was insane when he did it?
That seems pretty unfair to me...help you just enough so you can grasp you are in Court standing trial for something you did when you were not in your right mind.
