CNN reports he was shot in the head?

What do you think of the possibility that one of his bodyguards shot him? I remember watching an interview with one of Bin Laden's former bodyguards where he stated his orders were to do just that in case he was close to caputure. I also heard the gunfight lasted 45 min, so im sure they would of had time to do it if need be. And do you think the gov't would acknowledge this was the case if found to be true? Thanks.
