Why do you say that? I could see it only if his disclosure was of illegal acts and I have full confidence that these activities were entirely legal, in furtherance of the Presidents responsibilities for National Defense/Security. To boot, they were properly disclosed to appropriate oversight bodies in Congress. W's actions will only be deemed 'Illegal' in the MSM but not in any other legal forum IMO.
What I would really like to see is his imprisonment, a la Judith Miller, until he discloses his source. Then, let the games begin.
