1. Given Scooter's bald-faced and readily falsifiable tissue of lies, it is clear that these morons really must have thought that the Department of Justice would never go after -- much less secure -- testimony from reporters. Two potential explanations (not mutually exclusive) present themselves: (a) early in the investigation, when Scooter & Co. first confected the I-just-heard-this-as-gossip-from-reporters web of whoppers, the malefactors thought the fix was in because Ashcroft was running the show (and bear in mind that no Justice official had begun utilizing a grand jury); (b) there is a certain folklore around DC that prosecutors just won't go after testimony from reporters (whether out of principle or the feeling that it's not worth the fight and bother). Let's remember, shall we, Bush's little Freudian slip of October 7, 2003: "I have no idea whether we'll find out who the leaker is, partially because, in all due respect to your profession, you do a very good job of protecting the leakers." Very, very foolish gamble, dipshits.
2. "Official A" is, of course, Rove. We'll be hearing more about him before too long. My first instinct on the unnamed "Undersecretary of State" is Marc Grossman. But outside odds make it John Bolton. That would be delicious. "Goo-goo-goo-fucking-joob" indeed. But let's not get too greedy too soon.
3. Fitz is not done. He's probably not even done with Scooter. Scooter's love-letter to Judy deserves its very own count in a superseding indictment.
4. Any efforts to crank up the noise machine to go after Fitz will backfire, horribly. He's very, very good. And he's just doing his job. Very well.
