I assume that you read Greenwald's entire piece. I'm kinda curious why you left out several paragraphs of that particular update.

There are now a total of six updates. Greenwald appears to have serious doubts that the government isn't lying about Ivins being the mastermind and sole perpetrator. I found it interesting that Greenwald felt the need to add this one:

UPDATE V: I tried to be careful here to avoid accepting as True the matter of Ivins' guilt. Very early on in the article, I framed the analysis this way: "If the now-deceased Ivins really was the culprit behind the attacks, then that means that the anthrax came from a U.S. Government lab," and I then noted in Update II that Ivins' lawyer vehemently maintains his innocence. My whole point here is that the U.S. Government now claims the anthrax attacks came from a Government scientist at a U.S. Army lab, and my conclusions follow from that premise, accepted as true only for purposes of this analysis.

It's worth underscoring that it is far from clear that Ivins had anything to do with the anthrax attacks, and someone in comments claiming (anonymously though credibly) that he knew Ivins personally asserts that Ivins was innocent and makes the case as to why the Government's accusations are suspect. As I see it, the more doubt there is about who was responsible for the anthrax attacks, the greater is the need for ABC News to reveal who fabricated their reports linking the attacks to Iraq.

It sure seems like he he just couldn't have been the only one involved.

Update IV has interesting bits on roles McCain and Lieberman apparantly played in catapaulting the propaganda, too.

McCain discusses with Lettrman evidence that the anthrax came from Iraq - October 18, 2001.

Joe Lieberman went on Meet the Press (on October 21, 2001)

Probably too late to catch Greenwald live though, there may be an archive available:

UPDATE VI: I'll be on Rachel Maddow's radio show tonight at 8:30 p.m. EST to discuss this story. Local listings and live audio feed are here.
