It can be an attack and a decision to manage perception
Someone mailed anthrax. I think we can agree on that. One question is, who did so? At the time of the initial attacks, and for at least three years afterwards, the pool of suspects was in the tens of thousands in the US alone. (Every member of a large microbiological society was sent a letter asking them 'if you can think of anyone, would you tell us?' A joke, as bad as the Unabomber investigation.)
Did the attacks originate in the US? There was a turf war between various agencies on the answer to this question. Dueling experts from Ft. Detrick, the FBI, etc were being quoted, mostly anonymously. The schools of thought were largely "furrin divils" versus "local wingnuts."
At some point, not one but four independent government source were reported by ABC news to have said that bentonite had been found in the samples being analyzed, and further declared that the Iraqi weapon program used bentonite to weaponize anthrax.
That leak to ABC was deliberate perception management. It was instrumental in making the US more willing to attack Iraq -- a number of people are on the record as saying that they were swayed by the bentonite story. (Lots of good reporting in Salon on this topic.)
The White House had decided by the start of business September 12 that a return to Iraq was on the dance card. Bob Woodward reported that. The week of the 11th, the NSA was openly discussing perception management to channel people's responses to September 11. By 'openly discussing,' I mean 'in interviews broadcast on PBS that very week.'
Putting the anthrax on Iraq was brilliant. Low likelihood that the mailer was going to be busted in a relevant timeline. The mailer might even have ties to the middle east - no one knew at the time. Why not plant disinformation in the press?
Now we hear years later:
- no bentonite
- no silica of the sort which would be use for weapons forming
- local boy makes good. BTW, this local boy writes letters to his hometown paper, lots of them, that make him seem a lot closer in outlook to Dorothy Day than Tim McVeigh.
I'd like to see ABC come clean about who those four sources were, or at least -- if not divulge their identities -- have a chat and ask them for their responses to the death of Ivins, and also what the fuck they were thinking when they said 'bentonite' before. And yes, run a story about what those four had to say, now after the fact.
As for Ivins: I haven't taken time to read the transcript of the Q and A yet. What I know from what I have read is that they've done a good job of saying "the strain came from a flask in Ivins' lab" in a non-adversarial setting. No one to ask informed questions about chain of custody, about analytical methods, no one with time and background being paid to study the evidence presented.
Granting the FBI that flask still leaves them a long way from Ivins. In these labs, people wandered around and in and out on a very regular basis. (I had the opportunity to spend a little time at the facility in the mid-90s; yes, it's got strong military overtones - but at the end of the day, it's full of boffins with boffin habits.)
The reporting on lab procedures and sample handling throughout the case makes it very clear that they actually don't know who had access to what and when.
