U.S. drone strikes in Pakistan have killed far more people than the United States has acknowledged, have traumatized innocent residents and largely been ineffective, according to a new study released [on September 25]. The study by Stanford Law School and New York University's School of Law calls for a re-evaluation of the practice, saying the number of high-level" targets killed as a percentage of total casualties is extremely low -- about 2%. In contrast to more conservative U.S. statements, the Stanford/NYU report -- titled "Living Under Drones" -- offers starker figures published by The Bureau of Investigative Journalism, an independent organization based at City University in London. Based on interviews with witnesses, victims and experts, the report accuses the CIA of "double-striking" a target, moments after the initial hit, thereby killing first responders. It also highlights harm "beyond death and physical injury," publishing accounts of psychological trauma experienced by people living in Pakistan's tribal northwest region, who it says hear drones hover 24 hours a day. "Before this we were all very happy," the report quotes an anonymous resident as saying. "But after these drones attacks a lot of people are victims and have lost members of their family. A lot of them, they have mental illnesses." People have to live with the fear that a strike could come down on them at any moment of the day or night, leaving behind dead whose "bodies are shattered to pieces," and survivors who must be desperately sped to a hospital.
