They had a couple of months of CIPA proceedings to determine what classified information could come in and what could not.
The judge doesn't have the authority to simply decide that classified information can be revealed in open court.
And, if you are going to say there was nothing classified about it, if that were the case it wouldn't have been the subject of CIPA proceedings.
great circular reasoning there:
no one was charged with revealing classifed information. even the people who ADMITTED they revealed her employment status (Armitage, Wilson himself) and members of the press who repeated it, have not been charged or faced even the slightest scrutiny for it.
Yet, the CIPA proceeding found that Libby couldn't use information about Plame, because it's classified.
