The main suspect in the anthrax mailings post-9/11 committed suicide this past week, and there are a number of mysteries still surrounding the case. For example, it appears that a number of people were told to take Cipro in advance of the mailings. Also, ABC News claimed that four separate sources told them that the anthrax had bentonite included; this statement suggested that Iraq was the source of the agent. The whole thing is spooky, in multiple senses of the word. Glenn Greenwald has the details.
