This article asks some interesting questions.

In the weeks after 9/11, a lot of mail was sent with anthrax in them.  It resulted in the deaths of some people, and a nation wide fear that cemented the us-vs-them war on terror.

It was also a large part of the motivation for the war on Iraq (with ABC news first drawing the connection, then the State of the Union address, then Colin Powell in front of the UN).

Now they’re saying that the anthrax possibly came from a right wing, religious army scientist working at a military base?  Sketch.
