An investigation into detainee abuse reported by FBI agents at the U.S. detention facility at Guantanamo Bay, Cuba, has found no link between the alleged misconduct and Defense Department policy, according to military and congressional sources familiar with the investigative report.

Air Force Lt. Gen. Randall M. Schmidt and Army Brig. Gen. John T. Furlow are scheduled to brief senators this morning, but it is unclear how much information will be discussed publicly because the report is almost entirely classified.

Schmidt and Furlow looked into alleged misconduct witnessed by FBI agents working at Guantanamo over a two-year period, including shackling detainees to the floor in the fetal position for long periods of time, using military dogs to intimidate detainees and having military interrogators pose as FBI agents.

Sources discussed the report anonymously yesterday because it is classified. They said the report makes the same conclusion as other internal Pentagon abuse reviews in the wake of the Abu Ghraib scandal: that the abuse was not official policy and that blame does not rise to top leaders.

"It is more of the same, only instead of it being military police doing it for their own amusement, it's interrogators presumably doing it to gain intelligence," said one source who read the report. "It broadens the scope of all of this. It's not just a few rogue MPs anymore."

The other difference is that the incidents of abuse were documented by FBI agents instead of by digital photographs or by released detainees, who might have a reason to fabricate abuses. The sources would not say which claims were substantiated.
