Old Guy thinks that as long as Rove wasn't the FIRST to name names, then he's not the leak. If Rove named any manes at all about who is an undercover agent no matter who was the first, he still participated in the leak and is still guilty. He never went to trial as far as I know so he can still be charged later on without it being double-jeopardy. I think Fitzgerald is still eyeing Cheney and is willing to let Rove slide--at least for now.

Cheney has to be the original leak. We've known it since Libby's arrest.
