You know what? I agree with you in that if OBL surrendered, then they capture him and take him somewhere to extract all information from him that they can. But I also think that if he did not immediately indicate that he was surrendering, a bullet to the head was his just reward.
Group hug! Seriously, I agree completely here.
When they send the SEALs in, they're not going in to simply arrest someone. Is it that hard to understand?
I fully admit I have no military training. However, those I have spoken to, and most of those I read on message boards, who have such training claim (when the topic is brought up) that when a person surrenders, they are taken prisoner. I don't think that would be different for SEALs, but perhpas you have some knowledge of them I don't?
At any rate, I am 99% certain Osama was not executed. It's still important to raise the question.
