CBS’ David Martin explains in more detail that “Staff Sgt. Robert Bales was expected to be handed a charge sheet in the prison at Fort Leavenworth, Kan. officially accusing him of 17 counts of murder and six counts of attempted murder and aggravated assault. His attorney says Bales has no memory of the March 11 rampage in which he allegedly walked off a combat outpost in Kandahar province, shot and killed 17 people – including children – then returned to the base”, continuing that Bales’ “attorney, John Henry Brown . . . seems to be building a defense around the mental and physical toll taken by Bales’ four combat tours. According to Browne, Bales was involved in a total of nine roadside bombings and suffers from Post Traumatic Stress Disorder (PTSD), but Army mental health experts say there is no scientific evidence PTSD can lead to acts of violence. Browne says he is concerned Bales could try to harm to himself and that he is under 24-hour watch at Leavenworth”.
