I agree. The nature of the stuff is that only a handful of people knew how to make, and transmit this, efficiently. That's why Hatfill is such a suspect. He was involved in all sorts of training ops in the 1990s. It may only be that he showed someone how to do it who later turned out to be a terrorist, but it's suspicious.
1. Postal processing equipment tends to pulverize anthrax to an even finer character than the best commercial equipment designed to do the job.
2. It takes 2 to 3 days before the anthrax can begin leaking directly through the paper of a USPS embossed postage envelope ~ so they taped those envelopes up just enough to avoid having the anthrax spill out too early in the attack.
This means they had some pretty sophisticated support behind them. I'd suggest the Iraqis helped them directly by providing some pretty standard anthrax from their "samples" used for product testing. However, the Iraqis had earlier looted the Kuwait main post office and stolen ALL of their mail processing equipment. It was state of the art ~ best you can buy anywhere. I knew several men in the Kuwait post office who were hauled away by the Iraqi Army, presumably for the purpose of operating that equipment for the purpose of determining how it worked to aid or hinder a bio-war attack through the mail.
The attack was obviously planned with two major targets, and maybe as many as ten secondary targets in mind.
First, they sent the letters to addresses which would be routed through 6 major airports ~ 3 in New York and 3 in the Washington DC area. That is, the pieces would be routed, inside mail equipment (trays), through LaGuardia, Newark, JFK, Dulles, Reagan National, and Baltimore airports ~ which are the principal points of access to America's financial capital, that is New York City, and America's political capital, that is Washington DC.
What they didn't plan on was the letters getting misrouted almost immediately after mailing and traveling by truck to New Jersey in supposedly empty postal equipment.
However, that would simply have been the first targets ~ and only enough anthrax to scare the hell out of everybody in the country would have penetrated the envelopes and the trays carrying them.
Next came the main postal facilities in New York and Washington DC. By the time the letters got there they'd been pumping anthrax out by the millions of spores.
Well, the ones going to New York definitely got sidetracked, but the ones going to DC made it and totally contaminated the main postal processing facility for the capital city for the most powerful nation on Earth.
Some of us got the message. Some didn't.
Then, traveling on through the system, after having been worked over by postal machinery, the anthrax letters got to the main mail room at the US Senate. At that point they successfully contaminated about 15,000 Congressional employees. Although the numbers were never released, at least 10,000 postal workers had been contaminated. Lord only knows how many customers and transportation people were affected, but we do know some people died.
Alas for the terrorists, anthrax is not exactly the worst thing going in this day of Cipro.
If the attack had gone off as planned, at least 25,000 people on Capitol Hill would have died of anthrax. Another 800,000 people in the USPS would have died. Tens of millions of postal customers, particularly in the East Coast, would have died.
I'd suggest that ten more minutes planning and these guys would have pulled off the largest mass murder in history.
So, what were you saying about this not working?
