Actual risk to O.J.: Uncertain. It depends on what Simpson has been up to recently. If he'd raised money to help find his wife's killer, for example, he'd certainly be exposed to prosecution for fraud. We do know that O.J. has appeared in a sleazy DVD called Juiced, in which he makes frequent jokes about the murders and his trial.
If Simpson did end up in court, could his televised "hypothetical" confession be used against him? Yes. The fact that he's beginning every sentence with "If I did it … " might give him a little bit of wiggle room, but it doesn't grant him any kind of immunity. His hypothetical confession will still be damning if it reveals any new information about the case that only the killer could have known.
