Impeach George W. Bush. Impeach him now. Mark Kleiman:
The Reality-Based Community: Puzzle solved?: Why didn't Patrick Fitzgerald indict anyone for the substantive crime of revealing the identity of a CIA NOC?
Perhaps because he discovered that the revelation was done on the orders of the President, who (at least arguably) can't be indicted by a Federal prosecutor. Anyone down the chain (Libby, Fleischer, Rove) would have had a good defense that he or she was acting in good faith to carry out a Presidential order.
