I still think so. Our friendly neighborhood radical Islamist terrorists don't pull such silly, juvenile (and ultimately, harmless) pranks like the silly Anthrax "attacks."
When they do something, it's done with style, it's well-planned, and it is much more effective.
If and when they ever take it into their heads to stage a "bio-attack," I think thousands will die, not just four or five.
1. Who paid the rent/mortgage on the place for the last year? Did the dishes just sit there for a year and newspapers collect in the front yard since Sept 01? Further if they had a car, they probably had a drivers license and it sounds like 2 kids in local schools.
2. Why is the FBI making the connection now or in the last 2 weeks (took PC out 2 weeks ago)? My guess its related to either the raid on the UK mosque about a week ago or to information coming from the raid on the latest doctor's house in Pakistan about 3 weeks ago. There was a reference to his sons' having lived in Florida but the articles at the time gave no further specifics.
3. If they were tipped off on Sept. 9 and fled, then tip may have come by electronic communication from Afgh/Pak, Hamburg or directly from the hijackers. Does anyone know when and from where the anthrax was mailed?
