ROFL, yeah, that's why the FBI was unable to duplicate the proces that made it after two years.
Dr. Richard Spertzel said that there was only a small handful of people in the entire country with the knowledge to make that anthrax, and that he himself was one of them. In his own words, any country with that knowledge had "the keys to the kingdom".
No personal disrespect, but I take his word on it over yours.
