the more I read, the more it sounds like Joe Wilson might be Fitzgerald's target for perjury charges.
Wilson couldn't be prosecuted for his outrageous public accusations against Rove, but if he repeated them under oath, Fitzgerald would have known months ago that Wilson's allegations, (which spawned the entire investigation), were lies.
So, Rove warns Cooper not to believe Wilson, mentioning that the CIA was involved, blah blah blah.
Cooper leaps to the conclusion that it's Valerie.
What this tells me is that Cooper KNEW Plame was CIA.........ROFLMAO. And, of course, that means the whole town ALREADY knew it!
