When it eventually is revealed that the Anthrax attack was really the result of Islamic terrorism, I think we will need to have a sober discussion on the how politics got in the way of common sense in the Justice Department (Cough, cough, Black Panthers).
I’ve heard a rumor that the U.S. government knew the source of the anthrax attacks early on, and moved against the responsible party. According to the rumor, GWB warned the guilty party that any further WMD attack would result in a U.S. nuclear attack on Mecca — which is why no further such attacks have been launched.
