Maj. Gen. Geoffrey Miller has retired from the Army. On Monday he was awarded the Distinguished Service Medal, one of the Army’s highest honors. Miller is the general who oversaw the interrogation of detainees at Guantanamo Bay and Abu Ghraib. While at Guantanmo, Miller implemented a number of harsh interrogation tactics that included the use of dogs, the stripping of prisoners naked and the shackling of prisoners in stress positions to force them to talk. Such tactics later were used in Iraq. Miller had originally tried to retire in February but he was denied his request because there were a series of investigations and courts-martial underway. Army experts say it now appears unlikely that Miller will face any disciplinary action in connection with the Abu Ghraib abuse scandal.
