Report Details Dissent on Guantánamo Tactics

By ERIC LICHTBLAU and SCOTT SHANE

WASHINGTON — In 2002, as evidence of prisoner mistreatment at Guantánamo Bay began to mount, Federal Bureau of Investigation agents at the base created a “war crimes file” to document accusations against American military personnel, but were eventually ordered to close down the file, a Justice Department report revealed Tuesday.

The report, an exhaustive, 437-page review prepared by the Justice Department inspector general, provides the fullest account to date of internal dissent and confusion within the Bush administration over the use of harsh interrogation tactics by the military and the Central Intelligence Agency.
