Oh I don't know. Why not shoot someone from a distance?

I read "A History of Warfare" by John Keegan. It's quite interesting from the viewpoint that war in more primitive cultures was principally ritualised often with ranged weaponry, where both sides tended to try to avoid casualties even to the point where they might barely inflict any. Eventually one side would give up and go home. The suggestion he made was that was the original "natural" state, and where possible and without social conditioning or training humans want to revert to it.
