Eleven minutes to nine?
Interesting.
The attack was on a Tuesday. All the anthrax letters bore Tuesday dates.
I'm guessing "7" to be a significant number in this attack. July is the 7th month. Today is the 7th. There were 7 explosions which may be indicative of 7 perps.
If some of them were by remote, the bas***** are walking around London taking photographs.
