    The judge in the CIA leak case ruled Thursday that if Special Counsel Patrick Fitzgerald feels that admitting certain classified documents at the upcoming trial of I Lewis "Scooter" Libby can jeopardize national security, Fitzgerald can move to dismiss the perjury charges against Libby.


This could very well mean that the judge is telling Fitzgerald he doesn't have a case, and if he wants to save face, he'd better drop the charges. It could also mean that Fitzgerald may have realized his case is going nowhere and that he can invoke "national security" as a pretext for dropping itl, again to save face.
