Or maybe it wasn't domestic in the first place. Not sure why everyone is so anxious to pin it on conservatives and/or those with religious issues (such as right to life). If it does turn out to be domestic, my bet is on some left-winger like the Unabomber.

Yes, indeed, there are a lot of hateful whackos out there. But it's extremely doubtful that any of them have access to military-grade anthrax, stolen from one of three or four weapons labs, probably from a U.S. biowarfare lab.

Or, it could have come from a lab worker. I hadn't seriouly entertained this possibility until I read that as a matter of course, all government employees working on anthrax projects received vaccinations, which makes it a lot harder to find them by looking for someone who is sick from accidental exposure. Right now, I seriously think this is the most likely possibility.
