What I mean to say is that it doesn't matter to know who physically performed the actions, only to know who planned and directed it. Just like we might blame bin Laden for 9/11 even though he didn't fly the planes. He was on the other side of the earth. Or whatever, you get the idea.

But in any case, of course we don't know. But we should attempt to find what is and isn't a reasonable explanation, and what may be most reasonable.
