I think my feelings about this can be summed up with one word- concerned.

Great, we killed him. One less medium-large evil in the world. His machine is still out there and operating. And since we dumped his body in the ocean, Osama will be spotted about as often as Elvis. If only we'd bothered to bring out at least his head, at least then we'd have proof.

When a man dare not speak without malice for fear of giving insult, that is when truth starts to die. Truth is the truest freedom.
