Oh my. What a freakshow this guy is. You would think someone would have taken him aside at some point and said, "Hey Rusty, maybe you should just speak through your attorney."
You are suprised that a guy who had all his children murdered by his wife just a few years ago is still acting a bit strange?
I dunno, I'd be more creeped out if someone who had gone through that still isn't showing signs of it affecting them. For goodness sake, he's lost everything he had and everything to live for.
