It just occurred to me that the way ObL was shot supports the idea that the SEALs thought he might be going for a weapon. He is said to have come partly out of the room. Had he surrendered right there, unarmed, he might have been taken alive.
That he was not in full view supports a claim that he might have been going for a weapon.
I base the assertion that he was probably not in full view on the fact that he was shot in the head.
Military doctrine is very clear that one shoots for the center of body mass. Head shots are a bad idea. Too much chance you will miss.
I'm guessing that his head was the only part visible when they fired.
Don't you think it reasonable that they should assume him to be armed already considering the noise they had to have made already?
