It's been a bad week for American war criminals. Yesterday, a 20 year old Marine was sentenced to 18 months for taking part in kidnapping and killing an unarmed Iraqi man. The day before that, an Army specialist plead guilty to raping and murdering a 14-year-old Iraqi girl. That makes a total of at least 16 U.S. military personnel who have been convicted of illegally killing Iraqis since the war began. And we have yet to hear whether the Marine Corps will bring charges against its soldiers accused of massacring 24 Iraqis in Haditha last November.
