JED RUBENFELD: Yes, the Bin Laden Killing Was Legal. “Under any sane construction of the laws of war, his killing was lawful regardless of whether he ‘raised his hands in surrender’ or whether U.S. troops weren’t to give him the chance. . . . Most of the laws of war depend on a modicum of reciprocity: We give our enemy’s soldiers certain rights in the hope that they will do the same for ours. Men who make war on innocent civilians and behead their prisoners live by a different law. They should expect to die by it as well.”
