Yeah he's a thick skinned son of a gun.
I suspect there's nothing anyone could write that would get under his skin.
Each to their own.
The only thing anyone could write that would bother him in the least is a judge writing out his punishment and the length of time he'd have to stay in prison. So, since I think he's smarter than that, I don't believe anyone could really bother him no matter what they wrote - unless it caused others to begin to dislike him or falsely accuse him of something that could cause him real harm.
