Two former Blackwater security guards were arrested Thursday on murder charges stemming from a shooting in Afghanistan last May that left two Afghans dead and a third wounded, the Justice Department said... [The] arrests seemed to signal that the Justice Department did not plan to abandon its scrutiny of Blackwater [now Xe Services] despite its defeat in the Nisour Square case...[T]he two former guards…were arrested after being indicted…on charges of second-degree murder, attempted murder and firearms violations. At the time of the May 5 shooting in Kabul, the men were working for Paravant LLC, a subsidiary of Xe Services…Mark Corallo, a spokesman for Xe Services, said the company “immediately and fully cooperated with the government’s investigation of this tragic incident and terminated the individuals involved for violating company policy.”
