" he would be of far more use alive"
I don't think he was really in the operational loop by then. Of course he might have had some interesting stories to tell about who helped him in Afghanistan against the Russians etc
Anyway alive he'd have been a "cause" for every nutcase to be able to take hostages, anywhere in teh world and a constant source of "news" stories. Better he's where he is - tho I hope it involve standing in eternal security lines at airports in a warm place
