Federal prosecutors have announced they won’t file criminal charges against a former operative for the private military firm Blackwater accused of killing an Iraqi security guard in 2006. The operative, Andrew Moonen, was reportedly intoxicated when he shot and killed Raheem Saadoun, who was on duty protecting Iraqi Vice President Adel Abdul Mahdi. Moonen is the latest former Blackwater employee to evade prosecution. Last year a federal judge threw out all charges against five Blackwater operatives involved in the 2007 Nisoor Square massacre that killed seventeen Iraqi civilians.
