There is not any evidence, I repeat any, that he did it.
This is the same FBI team that blame two other scientists for the crime as well before they had to pay out multi-million dollar settlements for ruining their lives.
“Scientist Is Paid Millions by U.S. in Anthrax Suit
The Justice Department announced Friday that it would pay $4.6 million to settle a lawsuit filed by Steven J. Hatfill, a former Army biodefense researcher intensively investigated as a “person of interest” in the deadly anthrax letters of 2001.”
For nearly seven years, scientist Bruce E. Ivins and a small circle of fellow anthrax specialists at Fort Detrick’s Army medical lab lived in a curious limbo: They served as occasional consultants for the FBI in the investigation of the deadly 2001 anthrax attacks, yet they were all potential suspects.
They hounded Ivins to death:
[...]colleagues and friends of the vaccine specialist remained convinced that Ivins was innocent: They contended that he had neither the motive nor the means to create the fine, lethal powder that was sent by mail to news outlets and congressional offices in the late summer and fall of 2001. Mindful of previous FBI mistakes in fingering others in the case, many are deeply skeptical that the bureau has gotten it right this time.
“I really don’t think he’s the guy. I say to the FBI, ‘Show me your evidence,’ “ said Jeffrey J. Adamovicz, former director of the bacteriology division at the U.S. Army Medical Research Institute for Infectious Diseases, or USAMRIID, on the grounds of the sprawling Army fort in Frederick. “A lot of the tactics they used were designed to isolate him from his support. The FBI just continued to push his buttons.”
Ivins did not have the wherewithal to make airborne anthrax:
[...]others, including former colleagues and scientists with backgrounds in biological weapons defense, disagreed that Ivins could have created the anthrax powder, even if he were motivated to do so.
“USAMRIID doesn’t deal with powdered anthrax,” said Richard O. Spertzel, a former biodefense scientist who worked with Ivins at the Army lab. “I don’t think there’s anyone there who would have the foggiest idea how to do it. You would need to have the opportunity, the capability and the motivation, and he didn’t possess any of those.”
They did a very similar job on Hatfill - leaked very prejudical rumours about him to the media. But he was a stronger character, and faced them down.
Ivins seems to have committed suicide because they got hold of discreditable information about his sex life. He used to have a fetish for wearing women’s knickers, or something (and, therefore, he must be a bio-terrorist! YEAH!) He also used to buy pornographic pictures.
They were making all this public. He should have just faced them down, like that Flynt guy who publishes Hustler, and who said “America is the greatest country in the world, because America is the freest country in the world.”
