Not much, Frank. I mean, in the past, mob bosses who have been acquitted after being held without bail had no recourse, so why should he?

And you'd never make a "false arrest" claim stick because of his past. When you have a criminal past, your character isn't "unimpeachable." It's already tarnished in the eyes of the court. I don't think that's fair, but that's the way it is.

Don't forget that kind old "Uncle Joe" was once convicted of murder, and if not for a technicality ten years into his sentence, he would have likely died in prison. So that part of his past would probably hurt any type of lawsuit he might bring. But fuck, at this point he'd be THRILLED just to walk on these charges. Fuck the lawsuit.
