On request by the National Security Advisor Susan Rice in 2015, the CIA compiled a summary of key intelligence, which according to their records had been collected after the application of (unspecified) interrogation techniques. The memorandum lists intelligence related to the following topics: The Karachi Plot, The Heathrow Plot, The "Second Wave", The Guraba Cell, Issa al-Hindi, Abu Talha al-Pakistani, Hambali's Capture, Jafaar al-Tayyar, Dirty Bomb Plot, Shoe bomber, and Sh(a)kai (Pakistan). The CIA concluded that the enhanced interrogation techniques had been effective in providing intelligence and has been a key reason why al-Qa'ida has failed to launch a spectacular attack in the West since September 11, 2001.
