Too whom they were directed is totally irrelevant...IT's to WHERE they were directed....
Excepting perhaps Stevens...Somehow, I think that was "personal", something to do with ATTA...that Stevens was NOT part of the original plan and that someone "peppered" something that Stevens ingested.
When I was just looking up a link I read that supposedly they (Feds, I guess) are ready to release more information on this case shortly. I hope we gain more understanding of it. We have more unanswered questions than anything else.
NBC is reporting the big break was the development of DNA fingerprinting techniques that linked the attack anthrax to a specific container at Ft. Detrick linked to Ivins.
The pattern of anthrax contamination at AMI makes it pretty obvious it was related to something that came in through the mail room.
