Torture — that’s not what the U.S. is calling the Central Intelligence Agency’s sometimes fatal “interrogation tactics” like waterboarding, sleep deprivation and beatings. But that's what the public has named the practices outlined in a 6,300-page, $50 million Senate Intelligence Agency report on the CIA’s treatment of uncharged terrorist suspects and detainees following September 11, 2001. The report found that the brutal tactics were not effective and resulted in bad intelligence. It also found that the CIA had misled government agencies and the American public.

Nearly one in three of the 100 detainees in the CIA’s program were subject to interrogation tactics. The report detailed 20 cases. One detainee died of hypothermia after chained to a concrete floor with little clothing. Others were kept awake for days, forced into painful positions or shackles with their hands raised above them. Some were dragged naked and beaten. Five underwent what the report referred to as “rectal feeding.” Three were subject to waterboarding. Many were threaten, told they wouldn’t get out alive.

The report also revealed that the CIA had destroyed video evidence of interrogations; misinformed the White House, Congress, Justice Department and CIA inspector general about the program; and did not gain accurate intelligence to aid the CIA in stopping terrorist plots, as it led the public to believe in its justification of practices.

"This program was morally legally and administratively misguided," Chairman of the Senate Intelligence Committee Sen. Dianne Feinstein said.

The CIA has denied the reports findings, as Sen. Dianne Feinstein accused the agency of deleting files and spying on the committee as it conducted its investigations. Even after the investigation, the Justice Department announced that it would not bring new charges against the CIA.
