I am interpreting your post as saying Prosecutor Fitzgerald perpetrated a fraud upon the court, and the judge winked at, suborned really, perjury.
This whole Plame thing was such a crock of crap, it's turned into just another divorce court circus.
An honest judge is supposed to halt a proceeding when it goes off the rails, which explains why this has been in the news this many years.
The "Fitzgerald perpetrated a fraud upon the court" line of thinking is a good one to pursue - I wonder why Libby's lawyers are not going over Fitzgerald's statements to the judge justifying the expansion of his mission (and others) with a fine-toothed comb to find and highlight knowingly false statements that Fitzgerald has likely made to the court. Maybe that is the ace up their sleeve that they will pull out at the appropriate time if their other gambits fail. Fitzgerald has got to be sweating about that - and maybe a good deal of his bluster and his determination to continue the farcical prosecution of Libby is to distract attention from Fitz's own misdeeds. (with apologies for the mixed metaphors)
