Two more thoughts on the perfume lady and related incidents: I believe the incubation period for small pox is 10 to 14 days, which would put us sometime near the end of the Islamic Year if the "perfume" was small pox. But if it was small pox, there would be such large covergence of health care people to the area in addition to an air tight quarrantine, that the mainstream press would have to take notice.
Second, if AQ wants to go bio or chem, there are much more effective ways of maximizing exposure, than using a relatively small postal center. Releasing the stuff at a mass transit facility in NYC could potentially contaminate hundreds of thousands of people in a matter of hours, and allow the person spreading the stuff to do so without detection.
I will ever contend these postal finding's a re domestic terrorism as was the Anthrax
