Something I've been pondering over the past week or so, as we were getting a somewhat clearer picture of what went on around the Plame/Wilson leak: of course, it's verboten to reveal classified information that you know to be classified to someone not cleared for it. But is there a law that would cover the specific situation of someone who shares classified information with someone who is cleared for it, but doesn't tell them that it's classified, or at what level it's classified?
I'd think that may possibly be a very relevant matter in the (still!-)current investigation.
