Federal prosecutors in Washington announced Friday they will dismiss a manslaughter charge against one of the Blackwater contractors charged in a high-profile shooting incident in Baghdad, Iraq, two years ago. Channing Phillips, acting U.S. attorney for the District of Columbia, said his prosecutors had filed, under seal, a motion to dismiss the indictment against Nicholas Slatten. Reasons for the decision were not made public. Slatten…is one of five former military men who were working as guards for Blackwater Worldwide when they engaged in a deadly daylight shooting at a traffic circle in Baghdad.
