Don't swallow the guff about the anthrax being different in Florida. That was aerosolizable, military grade, too -- only maybe mixed up in a paste. It killed people, remember. Nobody in the entire history of the world had been killed by weaponized anthrax until a few days after a team of twenty Middle Eastern hijackers seized four airliners, knocked down both towers of the World Trade Center, ploughed into the Pentagon and tried to destroy the White House. Coincidence? I don't think so!
BTW, I think the anthrax sent to the hijackers' landlord was a goof. Seems like Atta had a very sick sense of humor.
A paste? That's the first I've heard of that. Is there a reference for this?
Also, don't be too quick to assume that the different mailings of anthrax were all the same. We don't know that either. As I've outlined elsewhere, the symptoms are different enough to suggest that there may have been differences in the anthrax between Florida and the Northeast. See my posts #13 and 14 on another thread for a discussion of whether the differences are statistically significant. The sample sizes are very small, making it difficult to demonstrate statistical significance, but it appears to at least approach statistical significance. (The difference between Florida and the Northeast with respect to the symptoms of long-term survivors is significant at the p=0.2 level [80% confidence level]. This isn't bad for such a small sample size. When you add in the differential rates of cutaneous vs. inhalation anthrax between envelope recipients in FL vs. NY, this will decrease the p-value and increase the confidence level further.)
