Geoffrey D. Miller (born c. 1949) is a retired United States Army major general who commanded the US detention facilities at Guantanamo Bay, Cuba, and Iraq.

"[citation needed] The U.S. Secretary of Defense Donald Rumsfeld on December 2, 2002, authorized in writing the "First Special Interrogation Plan," listing 17 techniques to be used on the detainee Mohammed al-Qahtani.

[4] On September 22, 2003, Miller ordered the arrest of James Yee, an Army captain who served as a chaplain for the Muslim prisoners at Guantanamo.

[7] In 2008, as a result of a joint Senate investigation by the Intelligence and Armed Services Committees, it was revealed that on March 14, 2003, John Yoo of the Office of Legal Counsel, Department of Justice, issued a legal opinion to William Haynes, General Counsel of the Department of Defense, in which he concluded that federal laws related to the use of torture and other abuse would not apply to US interrogators overseas.

Colonel Thomas Pappas, head of the military intelligence brigade at Abu Ghraib, has claimed that it was Miller's idea to use attack dogs to intimidate prisoners.

[12] In 2006, Miller exercised his use of the Fifth Amendment in refusing to answer certain questions while testifying in courts martial cases related to Abu Ghraib.

The next day Miller's testimony was directly contradicted by Lieutenant Colonel Jerry Phillabaum, the commander of Abu Ghraib's Military Police detachment.

[14] In November 2006, the German government received a complaint seeking the prosecution of Alberto Gonzales, then-Attorney General and former White House Counsel, for alleged war crimes.

[15] Co-defendants included: Geoffrey D. Miller, Donald H. Rumsfeld, George Tenet, Stephen Cambone, Ricardo S. Sanchez, Walter Wojdakowski, Thomas M. Pappas, Barbara Fast, Marc Warren, John Yoo, William J. Haynes, II, David Addington, and Jay Bybee, top political appointees who participated in making policy about the use of enhanced interrogation techniques for CIA and DOD.

On November 14, 2006, the German attorney Wolfgang Kaleck filed the complaint with the Public Prosecutor General (Generalbundesanwalt) against Miller for his complicity in torture and other crimes against humanity at Abu Ghraib prison in Iraq and Guantanamo Bay, Cuba.

The co-plaintiffs to the war crimes prosecution include: 1980 Nobel Peace Prize winner Adolfo Pérez Esquivel (Argentina), 2002 Nobel Peace Prize winner Martín Almada (Paraguay), Theo van Boven, the former United Nations Special Rapporteur on Torture, Sister Dianna Ortiz (Torture survivor, executive director of Torture Abolition and Survivors Support Coalition International), the International Federation for Human Rights, the International Peace Bureau (Nobel Peace Prize winner in 1910), the International Association of Lawyers Against Nuclear Arms (IALANA), European Democratic Lawyers, European Democratic Jurists, International Association of Democratic Lawyers, Comité de Acción Jurídica (CAJ) (Argentina), Liga Argentina por los Derechos del Hombre (Argentina), Bahrain Human Rights Society (BHRS), Lawyers Against the War (LAW) (Canada), Colectivo de Abogados José Alvear Restrepo (Colombia), Association Africaine des Droits de l'Homme (ASADHO) (Democratic Republic of Congo), Egyptian Organization for Human Rights (EOHR) (Egypt), Ligue Française des Droits de l'Homme (LDH) (France), The Republican Attorneys' Association [de] (RAV) (Germany), Amman Center for Human Rights Studies (ACHR) (Jordan), Comisión Mexicana de Defensa y Promoción de los Derechos Humanos (CMDPDH) (Mexico), Liga Mexicana por la Defensa de los Derechos Humanos (LIMEDDH), Centro Nicaragüense de Derechos Humanos (CENIDH) (Nicaragua), Palestinian Center for Human Rights, Association Tchadienne pour la Promotion et la Défense des Droits de l'Homme (ATPDH) (Chad), Rencontre Africaine pour la Défense des Droits de l'Homme [fr] (RADDHO) (Senegal), The Center for Constitutional Rights (CCR) (United States), National Lawyers Guild (NLG) (US), Torture Abolition and Survivors Support Coalition International (TASSC) (US), and Veterans for Peace (US).

[16] On April 2, 2015, the Court of Appeal of Paris ordered a first hearing of Miller to be conducted before a French magistrate prior to potential prosecutions.

[19] In July 2005, discrepancies emerged between Miller's May 2004 testimony to the Senate Armed Services Committee, and sworn statements he made three months later.

[20][21] On May 19, 2004, Miller had testified to the committee that he had only filed a report on his visit to Abu Ghraib, and didn't talk to Secretary Rumsfield or any of his top aides.

[22] The Washington Post reports that Miller had wanted to retire in February, forgoing trying for promotion to lieutenant general, because his reputation had been damaged by alleged links between his policies at the Guantanamo Bay detainment camp and at Abu Ghraib, and the abuse of prisoners.
