Then What Happened? (Score 1)

Ok. Let's assume that the FBI is right and that Ivans engineered all of this... to test his vaccine... that he never tested. Sure, that makes a lot of sense. And maybe he just happened to kill himself as they were about to seal the deal, cuz he was so guilty... and not because he'd been hounded to death after helping the government from the beginning. Bush is still president and Polosi says he didn't commit any crimes, so anything is possible... How did the anthrax get from its liquid state into the fine and specially formulated powder that went out in the USPS? Did Ivans do that? All by himself? With what and when? An EasyBake Anthrax Oven while pretending to make a beer run during church bingo?
