The former Blackwater security guards charged with manslaughter in a shooting in Iraq want the U.S. Supreme Court to reverse a decision that revived the stalled prosecution…Lawyers for the guards filed a petition in the high court Friday under seal, according to court records in the U.S. Court of Appeals for the D.C. Circuit…Much of the litigation in the case…was conducted under seal in 2009 because of the confidentiality of the statements that make up the centerpiece of the pitch to the Supreme Court…At issue is whether the indictment is tainted from the prosecution’s use of statements the guards were compelled to make in the hours after the shooting in Baghdad in 2007.
