Really? You want to turn the guy into an even bigger martyr and endanger innocent lives by giving extremists a reason to fight against a morally corrupt USA? The situation was handled exactly as it should have been with such a high value high profile target. You can't risk giving a terrorist organisation reason to turn the guy into a martyr or his gravestone into a place of worship/pilgrimage for future terrorists.
How narrow sighted can people be. If he was not dead do you think al-Qaeda would allow such a moral victory over them? of course not he would be out to refute it, they would refute it ect.
