yes I think there is a difference between the two.
But both can be bad. Although I would point out...that Matt Cooper claims he was outright told by rove about valerie plame, I agree that we in the public certainly dont know what the facts of the matter are, but its pretty clear to me, based on the white house statements alone, that the white house knows it did something bad, or else they would have been much more upfront about this whole matter 2 years ago.
Then, I think they were clear. I'm just not sure the press was listening.
