I've been trying to figure out how Fitzgerald could conduct a trial against anybody involved in this for any reason whatsoever and hope to get a conviction when the CIA is going to be in there quashing all requests for information about Plame's real job!
If the IIAP law had actually been broken, it would have been easy enough for Fitzgerald to have Plame as well as some top level person from the CIA confirm her status (as covert) at the CIA.
That's all it would have taken. So I don't see that as being any kind of an obstacle.
I think it's very clear from the preponderence of the evidence (such as we've heard) and the press accounts that there was no "leak" in the sence of the Agee/IIPA law.
That's why everyone in the DNC/media has moved on to hoping there was some slip up in testimony so that they can salvage at least a perjury charge out of all of this.
It's pretty pathetic, really.
