Really, I mean what in the hell could be in ANY documents whatsoever, that might in any way, shape, or form, change what he has done?
It's not like he's been screaming "Frame-Job!", or denying anything. He's rather proud of his handiwork.
I guess the only thing that could come out of any type of paperwork, would be that he was insane, and shouldn't die because of that.
Of course, I doubt any medical-type folks would say he was insane. He seems quite lucid, knowledgable, dedicated, and proficient.
I think a good idea would be to send him to Texas, and let a bunch of rich Texans auction off the right to put a .308 in him. Then the money could be used to help the families involved or something.
