That might be the case, but it's hard to blame people for taking a position like that.
Let's go back to Sunday evening before the official announcement was even made. The initial media reports were that Osama bin Laden had been killed in a Predator strike a week earlier -- and that the White House had waited until DNA tests confirmed his identity before making an official statement on the matter.
Then Obama gets up there and goes to great lengths to say he authorized the mission "today" (i.e., last Sunday) -- which led some of us (me included) to wonder if Obama's "live" appearance on Sunday night was actually taped the previous week and some incompetent fool didn't get all of the facts in order before presenting this "live" address. The fact that Obama gave his address on Sunday night nearly an hour after it was originally reported to be taking place fed the skepticism even further.
I also think this operation was too involved with too many people for it to be untrue. Occam's razor and all that.
If it's not true, proof of that would come out. For myself, I'm comfortable and happy with OBL's death. I'm still very uncomfortable the way they are spinning and using it.
