Wilson/Plame would get fried in court, should the case ever get that far, which it won't.
You are absolutely right. I keep seeing suggestions on leftist web sites that the Wilsons should sue Rove in some civil action. Not a chance they would do that as that would expose them to discovery. And they can't stand that heat. Plame is clearly not the brightest bulb on the CIA tree--then again, missing the end of the Cold War and WMD in Iraq, maybe she is. And that's a bummer IMO.
