WASHINGTON — The U.S. military hid the locations of suspected terrorist detainees and concealed harsh treatment to avoid the scrutiny of the International Committee of the Red Cross, according to documents that a Senate committee released Tuesday.

The administration overrode or ignored objections from all four military services and from criminal investigators, who warned that the practices would imperil their ability to prosecute the suspects. In one prophetic e-mail on Oct. 28, 2002, Mark Fallon, then the deputy commander of the Pentagon's Criminal Investigation Task Force, wrote a colleague: "This looks like the kind of stuff Congressional hearings are made of. ... Someone needs to be considering how history will look back at this." The objections from the Army, Navy, Air Force and Marines prompted Navy Capt. Jane Dalton, legal adviser to the then-chairman of the Joint Chiefs of Staff, Gen. Richard Myers, to begin a review of the proposed techniques.
