Iraq War Debate Weirdness

Now this is truly bizarre:

NEW YORK It was bound to happen sooner or later, and in what newspapers in Kentucky are calling a first, one American has killed another in a dispute over the Iraq war. It happened at Floyd County flea market on Thursday, when two friends, who were firearms vendors there, drew guns after quarreling about the war. Douglas Moore, 65, of Martin, who backs the war, shot and killed Harold Wayne Smith, 56, of Manchester, who opposed it, according to investigators. Moore was released without being charged after he convinced police he had acted in self-defense. A grand jury may yet hear evidence in the case.

Now, that is strange. I wonder what all the facts are.
