This week, a U.S. marine shot a wounded Iraqi prisoner in Fallujah, and an NBC reporter caught it on film. Now the video is being watched in homes thousands of miles away from where dead bodies are booby-trapped and shots burst from rubble.

While the iron-clad rules of war apply in the smashed streets of Fallujah, the line in the sand that soldiers are well trained not to cross is sometimes hard to find. In a battle where it’s often impossible to tell if there’s an AK-47 or a white flag underneath a billowing burqa, U.S. soldiers sometimes make bad decisions.

Hear an in depth look at the rules of war versus the realities on the ground in Iraq.
