"Using any kind of force means accepting that the target may be killed"
I have not questioned the use of force.
I have not questioned the possibility of death because of that.
What I have questioned right from my very post on this thread is that it could in anyway be "moral" or "right" to deliberately throw justice out of the window and to summarily execute OBL.
Dying in a firefight is one thing, being shot because he seemed to be going for a weapon or he was "resisting" is similar. If he was captured, taken into a soldiers custody and then just shot then I think it's pretty obvious that a line has been crossed.
"I heard a report that the US had ruled out the use of drone attacks on the compound"
Yes they did, but that doesn't imply anything about whether or not they had any intent on capturing him or were just going for an assassination.
And again right now I'd like to emphasise that we have no idea of what really went on. However my personal opinion is that I cannot believe that the US went in there with the specific intent of killing him no matter what happened. If we've slipped that far than AQ has won and we have lost.
