Well, I grant you I have wondered the same thing. Lots of strange details in his story. But I am thinking that also innocent people have trouble explaining their motives, especially under such intense scrutiny as this. If he were simply angling for a position that improved his lot in life (which I think he was) even exposure of that fact is personally embarrassing. I don't think his motives were pure, perhaps, but I don't see him as a gun runner.
