What do they mean by that? Eventually, there is only one person whom Nifong can hang out to dry if he wants to save himself and that's Mangum. He's gong to claim that he can't be blamed for having believed her.
They keep saying that he can sacrifice the cops to make his case. They are talking about the cop who was talking to his wife on the cell phone about the 20 guys. They say that they can hang this guy out to dry saying he was lying or talking out of school or something. The more we see though the more cops he will have to discredit. Since Crystal tried to run over a cop, I wonder how long these guys will stick with Nifong and as things get worse for him it might prompt a return of the Police Chief to this world.
