A plea deal has been reached in the court martial case of Marine Staff Sgt. Frank Wuterich. He was the last person facing charges in the killings of 24 Iraqis at the village of Haditha in 2005. Monday, he admitted to one charge of dereliction of duty. The case became a touchstone for criticism of the Iraq war. Originally, several Marines were charged with murder in the case. But the Marines who killed the Iraqi civilians that day claimed that their actions were tragic — but legal under the official rules of engagement in a complex war fought in and among the people. Melissa Block talks to NPR Pentagon correspondent Tom Bowman for the latest.
