Another Atrocity in the War in Afghanistan

It's one of the worst war crimes by an American soldier: Sergeant Robert Bales is accused of leaving his base in a remote part of Afghanistan, brutally murdering 16 civilians, including 9 children, and trying to set their bodies on fire. Bales reportedly returned to base afterward and asked for a lawyer. He'll likely be tried by the military at Fort Leavenworth, Kansas. Does he have Post Traumatic Stress Disorder? Is he himself a kind of war victim, or is he a cold-blooded killer who can't be excused in any way? These and other questions will haunt the longest war in American history until long after it's over. We hear some of the early answers today.
