Not so sure PP, if it had been a spur of the moment thing maybe, but he planned this for years and knew the outcome. He wanted his time in court, and the fan mail he has undoubtably recieved will boost the ego.

You may be right Charon, We may a have better idea on his state of mind when/if he reacts to his conviction and sentencing.
Can I be the first to suggest him onto the Deathlist 2052!!!
