Was it murder or battlefield justice? In 2007, there was an execution at a canal in Baghdad. Three decorated U.S. Army sergeants shot and killed four Iraqi detainees their platoon had taken into custody earlier that day. The soldiers are now serving prison terms at Fort Leavenworth. During interrogations the soldiers blamed military policy for making it too hard to detain suspected insurgents. We tell the story of the murders through one of the soldiers who was at the canal.

We also show you what the Army does not want released – part of the confession of one of the sergeants on an Army interrogation videotape. We obtained more then 23 hours of tapes in which interrogators interviewed the soldiers who were part of the mission that day in Baghdad. Don’t miss the first part of this 360° special investigation tonight.

Michael Scott, the Chicago Board of Education President, apparently shot himself in the head near the Chicago River before dawn yesterday morning. The school board president had said in August that he had been subpoenaed to testify before a federal grand jury investigating allegations of politically influenced admissions to top schools, but authorities did not immediately make any connection between the legal case and his death. Meanwhile, his death was met with disbelief by civic leaders and U.S. Secretary of Education Arne Duncan.
