Supposedly Fleischer realized that technically his involvement could constitute a capital offense. I don't know why, but I find that hilarious. Nobody's going to hang for high crimes for this. I'd be surprised if anyone besides Libby does any time, and even he won't do more than a couple years in Club Fed. Probably not even that.
It just doesn't matter -- the interest of the DC pols and the media weasels in this up to their greasy jowls militates toward punting this one as some inside-baseball sort of thing. There's no upside for either group to help unravel this mess, because it would clarify the real situation, that the latter group happily permitted themselves to be useful idiots for a mendacious administration that needed to micromanage the narrative, and get the war they wanted.
