A years-long legal fight over a deadly mass shooting of civilians in an Iraq war zone reaches its reckoning point, when the former Blackwater security guards are sentenced for the rampage. Three of the guards, Heard, Liberty and Slough, face mandatory decades-long sentences because of firearms convictions. Slatten faces a penalty of life in prison after being found guilty of first-degree murder. (AP Photo)
