The lingering question is why at sea?
The official said that finding a country willing to accept the remains of the world’s most wanted terrorist would have been difficult, so the decision was made to bury bin Laden at sea. Furthermore, one suspects that the U.S. would not have wanted there to be a physical grave site for fear of it turning into a place of worship for bin Laden’s followers.
It’s also believed that DNA testing would have been carried out beforehand to verify that the body was that of bin Laden, as well as being proof against any conspiracy claims that could emanate to suggest that his death didn’t take place. The exact location of the burial was not revealed. (via ABC)
