Yes. Osama bin Laden, while a fugitive from American justice, was not engaged in any life-threatening action at the time. The proper course would be to see that he's taken into custody.
I still believe in a nation of laws, for what it's worth today. And in America it's criminal to kill someone without sufficient reason; regardless of who or what that person is. That's the rule of law. And that's what we conservatives preach every day. We talk the talk, we have to walk the walk.
