One former senior official with Ivins' employer, the U.S. Army Medical Research Institute of Infectious Diseases, whom the FBI questioned at length about Ivins, said he believed his former colleague wanted more attention -- and resources -- shifted to biological defense.
"It had to have been a motive," said the former official, who suspects that Ivins was the culprit. "I don't think he ever intended to kill anybody. He just wanted to prove 'Look, this is possible.' He probably had no clue that it would aerosolize through those envelopes and kill those postal workers."
See, Ivins just wanted to make a fast buck, he didn't intend to kill anyone; he obviously could not have expected anybody at the destination address to ever open these letters that were all chock-full of weaponized anthrax spores. Say what?
