I dont know of any good documentary's about this, but there are prolly a couple.

But it was definitely a inside job. There was no way it wasnt.

Each strain of anthrax has its own signature I guess and they traced the anthrax back to a guy who was born in ohio and worked for the government.

WASHINGTON – Months after the anthrax mailings that terrorized the nation in 2001, and long before he became the prime suspect, Army biologist Bruce Ivins sent his superiors an email offering to help scientists trace the killer.

Already, an FBI science consultant had concluded that the attack powder was made with a rare strain of anthrax known as Ames that's used in research laboratories worldwide.

In his email, Ivins volunteered to help take things further. He said he had several variants of the Ames strain that could be tested in “ongoing genetic studies" aimed at tracing the origins of the powder that had killed five people. He mentioned several cultures by name, including a batch made mostly of Ames anthrax that had been grown for him at an Army base in Dugway, Utah.

Seven years later, as federal investigators prepared to charge him with the same crimes he'd offered to help solve, Ivins, who was 62, committed suicide. At a news conference, prosecutors voiced confidence that Ivins would have been found guilty. They said years of cutting-edge DNA analysis had borne fruit, proving that his spores were “effectively the murder weapon.”

Why do I think it was a inside job and not the work of one crazy fool?

Because that anthrax was mailed to people who were holding the votes up to pass the "patriot act".
