I suspect that the anthrax attacks were part of the 9/11 attacks.
They were too close in time to 9/11 and I don’t believe in coincidences.
If the Ames strain was in Canada or Sweden then it was in Russia and Iraq. Biologists ship each other bacterial strains all the time.
Also, Atta was seeking out crop dusters. If he was trying to get a crop duster he probably already had something to put in one, right?
It wasn't a "coincidence." Ivins evidently wanted to warn America of the danger that al Qaeda could launch a bioweapons attack next. So, he sent the anthrax to the media in letters that looked like they were written by Muslim terrorists. It's his reaction to 9/11, not a "coincidence."
"If the Ames strain was in Canada or Sweden then it was in Russia and Iraq. Biologists ship each other bacterial strains all the time."
The Ames strain was in Canada and Sweden, but only 2 labs in the U.S. had the Ames strain that contained the same mutations that were in the anthrax letters. So, the attack anthrax couldn't have come from those samples in Canada or Sweden.
Ivins prepared a special batch of 30 trillion anthrax spores to use in tests at Ft. Detrick. He thought those spores were untraceable and identical to samples that the USDA gave to anyone who asked for samples. But, Ivins was wrong. Those 30 trillion spores contained mutations that identified Ivins' flask RMR-1029 as the unique source for the attack anthrax.
"Also, Atta was seeking out crop dusters. If he was trying to get a crop duster he probably already had something to put in one, right?"
Yes, and what he was thinking about putting in them was GASOLINE. He looked into ways to put extra tanks of gas in the back of the plane. He was evidently planning to use the crop dusters as flying bombs, to fly into buildings somewhere. Then they got a better idea - to hijack airliners and use them instead.
Spreading anthrax via a crop duster is possible, but you'd need HUGE amounts of anthrax. There's no evidence that they had such amounts or any capability of making such amounts. The letters contained less than 3 grams of anthrax spores in total. There are 28 grams to an ounce.
