It's funny how the first people to throw around "possible motives" are always the ones who get it absolutely wrong. They get it so completely wrong with all their guesses it's almost as if they weren't guesses at all, but intentional deception. It's pretty obvious at this point to anyone who can think that this guy Ivins was a Mossad asset. He was a Jew carrying out a false-flag operation as Jews do, he pretended to be a muslim terrorist, he and his government pals wanted to...remove...a certain muslim researcher, while manufacturing some more fear of muslim "terrorism" to get the American goyim more enthusiastic about letting themselves be slaughtered in Jew wars for Israel. Oh, you thought your "soldiers" use those pathetically insufficient body armors and faulty rifles cuz there's not enough money? And so it goes. I'm not ruling out the possibility that this Ivins guy and his Zionist Bolshevist friends do this sort of stuff just as naturally as lions eat sheep, instinctively, but there may have been another motive for it as well. They don't want their enemies, muslims and other goyim, standing around when they're developing sophisticated biological weapons to take out entire races of humans, perhaps only sparing the God's Chosen, the Master Race by any other name. The Jews were the real "Nazis" all along. Fools.
