Helped in the development of cold water interrogation techniques

Water dousing the fifth most severe method of interrogation, according to a CIA manual, and involves immersing detainees in cold water at 5 to 15 C for up to an hour—about two-thirds of the time it takes to develop hypothermia in healthy adults. Christine Collins, president of the Union of Canadian Transportation Employees, called the CIA’s use of the manual “appalling.”
