Drone Papers

The Drone Papers is a leak of national security documents published by "The Intercept" in October 2015 on the United States's use of drone warfare. The leak revealed the bureaucratic process of approving a drone strike. In one five-month period, the primary sources showed that 90 percent of United States drone killings were "not the intended targets".
