It appears there is a great way to tell who is a "bad guy" so you can kill him. Just bait an area with wire, ammunition, etc, and if an Iraqi picks it up, shoot him. http://www.washingtonpost.com/wp-dyn/content/article/2007/09/23/AR2007092301431.html?hpid=topnews This is a pretty loose way of weeding out the "bad guys", IMO. If I found a roll of wire in the road, I'd be tempted to pick it up and take it home with me. That can get you killed in Iraq.
