Remember that a reporter for the Times went to jail and Fitz knew all along who leaked the name, and let people twist in the wind. Even though these dimwits will continue to hate President Bush, and even though they still want to damage him, Rove, and Rumsfeld, at some level, somewhere, somehow, a lot of people are livid now about this stunt by Fitz. It has turned into one of the most arrogant, brutal, and abusive uses of prosecutorial discretion in a long long time, even including that dumbass in Durham.
Also, remember how when Miller finally agreed to testify, she apparently negotiated an agreement with Fitzgerald that her testimony would be limited to her contacts with Libby only? So, at that time, Fitzgerald knew that Armitage was the leaker, but he agreed not to ask Miller any questions about her possible dealings with Armitage. Fitzgerald was amazingly uncurious about the original underlying basis for the inquiry, and was focused with tunnel vision on trying to screw Libby to the wall, even though he knew that Libby was not the originator of the leak. Again, the phrases 'overzealous prosecution' and 'prosecutorial misconduct' come to mind...
It was known that a CIA officer's identity was blown, it was known that there was a leak. We needed to figure out ....why.....
And, given that national security was at stake, it was especially important that we find out accurate facts.
Fitzgerald began his investigation accepting that Plame's identity was blown. He never doubted Wilson's (and the Left's) claims. He wanted to know why it happened (again accepting Wilson's premise that it was punitive) rather than proving it even did happen.
There was no national security at stake, and the fact is Fitzgerald already knew "who" leaked and was misleading the public when he said it was Libby.
This deserves much more attention than it is getting.
