In the AP Photo by David Guttenfelder, a U.S. soldier arrests an Iraqi man for alleged looting. Iraqis say what is most distressing is their physical treatment during and after arrest. U.S. troops put their boots on the back of men's heads as they lay facedown, forcing their foreheads to the ground. There is no greater humiliation, they say, because Islam forbids putting the forehead on the ground except in prayer.
