the father was decapitated

Sergeant Mejía recounted an incident in Ramadi in July 2003 when an unarmed man drove with his young son too close to a checkpoint. The father was decapitated in front of the small, terrified boy by a member of Sergeant Mejía's unit firing a heavy .50-caliber machine gun. By then, said Sergeant Mejía, who responded to the scene after the fact, "this sort of killing of civilians had long ceased to arouse much interest or even comment." The next month, Sergeant Mejía returned stateside for a two-week rest and refused to go back, launching a public protest over the treatment of Iraqis. (He was charged with desertion, sentenced to one year in prison and given a bad-conduct discharge.)
