Don't overthink this.
Some of the 9/11 hijackers had cutaneous anthrax. Remember the doctors and pharmacists who came forward after 9/11 and identified them?
The first man to die of anthrax in October 2001 was the employee of the man who rented rooms to the hijackers.
Coincidences like that don't just happen.
Peach, I may be "overthinking"-but I've sure been underthinking about this in the past.
Sorry ! I don't find any AQ laddies hiding under the bed on this one any more.
BTW: Don't you think they would have gloated about their success in the last 4 years ?
