Okay, I can't stand Clyburn, but I honestly think this is a misrepresentation of his point. Here's what he actually said:
CLYBURN: As long as it takes. Even if he doesn't come around to committing to a fair trial, keep those articles here. So keep it as long as it takes. If you know and he's told you what he's going to do, let's give him a fair trial and hang him. It's the reverse of that.
His point is that having a trial in which you've already decided the accused is innocent is an injustice, and "the reverse" of the often-criticized phrase "give him a trial and hang him." I don't agree with him, but in fairness, he is not endorsing the concept of "given him a fair trial and hang him." He's criticizing it.
