Is there not a moral equivalency to be made here? Which is more "moral" in your opinion... waterboarding a terrorist for information that DID save American lives... or assassination of an unarmed man in his home, in a foreign county, without their permission to be there, without UN approval, conducted by the CIA in charge of military special forces in a covert operation? Which is "moral" and which is not? Are they BOTH moral? Are they BOTH immoral? I think there is a moral equivalency argument here, and you are running from it.
You somehow don't want to acknowledge that enhanced interrogation worked, saved lives, gave us OBL.... but it's okay that once that worked for us, we went in and executed him. It's funny.... water on the head would have been "torture" but blowing his brains out without so much as a trial.... meh, no big deal, right? I guess killing him was preferable morally than bringing him to that god-forsaken Gitmo, huh?
