Providence, R.I. – The ethical debate over the use of so-called enhanced interrogation techniques on detainees in the U.S.'s fight on terrorism may never be settled. But a new report from the group Physicians for Human Rights adds a new element to the discussion. The group says its analysis of previously released records shows doctors were used in a Bush-era interrogation program to refine techniques such as water boarding. The aim, the group says, was not to protect detainee health but to make sure the techniques did not violate Bush era torture definitions. Doctor Scott Allen is a medical adviser to Physicians for Human Rights and the lead medical author of the report. He's also a clinical associate professor of Medicine at Brown University and co-director of The Center for Prisoner Health and Human Rights. He spoke to WRNI Morning Edition host Bob Seay about the report.
