Done. I can't see even a tenth of what you are postulating. There is a much simpler explanation for 9/11: a loosely organized group of fanatics carries out an unanticipated attack. Total cost: living costs plus flight training. Total communication required: "Here's the plan...", "Are you ready?", "We'll do it next Tuesday".
I think the anthrax was more complicated and find it hard to believe the rogue scientist theory. On the other hand, I don't think it required state sponsorship.
Yes, you can grow anthrax easily. But that is not the same thing as converting anthrax goo into a weapon.
To be a weapon the anthrax must be easily dispersed in the air, and the particles must be small enough to get deep into the lungs. Anything less will not be an effective weapon.
To convert the goo into a very fine powder that does not stick together is very difficult. Making small particles is difficult, and coating or otherwise treating them to eliminate static cling is even harder. You cannot do this in a bathtub.
Some of the anthrax used against us was "very high grade", meaning the particles were very small and treated to eliminate static cling. They could have been dispersed in the air very easily.
Very few nations have the capability to make the stuff that was used against us. Russia and Iraq are on the list, but few others. NO ONE could have done it in a bathtub.
The above info is in the public domain, but usually overlooked by our news media. When the Bush admin decides the time is right, I expect to see this info start to "leak" out.
