What he did then: Staff Judge Advocate for Combined Joint Task Force 7

What he does now: Serves in the Office of the Judge Advocate General for the Army in Washington, D.C.

Reported involvement: As Sanchez's chief attorney, Warren vetted many of the key detention and interrogation policies used in Iraq, including those specified in memos dated Sept. 14, 2003, and Oct. 12, 2003, that authorized the use of stress positions, sleep deprivation, and dogs. Warren also served on the Security Internee Review and Appeal Board, established in August 2003, that decided whether to release detainees who were deemed not to be a security threat or of further intelligence value. Army investigators reported their belief that members of Warren's staff, and possibly Warren himself, knew about potential abuses and misconduct in violation of the Geneva Conventions at Abu Ghraib but did not pass this information up to Sanchez or anyone else.

Punishment: The Army's chief lawyer clearedWarren of any professional impropriety under legal ethics rules and also cleared of him of the charge that he was derelict in his duties.
