Comment: This guy is a prime example of why being judged "mentally unfit" to stand trial should be abandoned. Similar to the designation "hate crime" - the perpetrator should be judged on the crime, not his ability to understand that it was wrong, or his motives.
Our system is becoming more over populated by the day. We must insist that our laws be kept simple, with no "what if" or "buts" that serve primarily to complicate things for everyone. Disarm them, lock 'em up and deliver punishment as per the law.
