First, I believe that bin Laden died long before May 1, 2011. In addition, I strongly suspect that he was not killed at all. In my opinion, he probably died some time ago from kidney failure or something related to the fact that his kidneys had ceased to function.
In my opinion, the Obama crew decided to release information that "they killed the big bad wolf story" solely for political gain. And because of what could be described as the defense of national interest, there is nothing that such entities as the C.I.A. and the former Bush administration can do about it. They have no other choice but to let the lie fly.
