"Among other appalling details, the report states that at least seven of the tortured detainees provided no intelligence at all. Many of those tortured unsurprisingly provided faulty intelligence, and none provided any intelligence that could not have been obtained through other methods. It prevented no terrorist attacks, and didn't contribute to finding any terrorists. Even when judged on its supporters' own terms, the program was a total failure. Dozens of people were tortured over a period of several years for nothing. In addition to being evil and illegal, it was all completely useless."
