I’m not convinced of Ivins’ guilt. I have a vague recollection that I read somewhere yesterday or the day before that Ivins was working on an athrax vaccine. If he were opposed to vaccines, then why would he be trying to develop one. The FBI was suggesting that Ivins had a financial motive for the anthrax mailings and that he wanted to scare lawmakers and the public into funding vaccine research.
I’m too lazy at the moment to try to find where I read such. I could have heard it on the radio. Who knows! :-)
That's one of the "theories" about "motive" that FBI is throwing out, but it's very doubtful. Ivins was on the "inside" and after the attacks could simply suggest this to appropriate people without raising his profile, and he was smart enough to know to keep low profile, yet he seemingly was doing exactly the opposite, writing letters and emails. There was enough panic about anthrax and potential follow-up attacks and daily talks about Cipro and vaccines.
Now, the "avian flu" and need for vaccine or facing the death of quarter of Earth population, on the other hand, was mostly hype.
