It's kind of similar to what we've all heard about all money being tainted with cocaine. Maybe it's the same with Anthrax; maybe it's in more places than we'd normally think.
Mind you, I am not discounting that there is some effort underway with some group to spread Anthrax. I'm just not convinced it is related to the 9-11 happenings. Since the known intended victims were liberal media or democrats, I am a tad concerned it is some internal US group doing it. Not saying it's a VRWC, but some militant US group.
