The news that the United States tortured prisoners in the war on terror has brought shame to the nation, yet little has been written about the doctors and psychologists at these prisons. In Oath Betrayed, medical ethics expert and physician Steven H. Miles tells how doctors, psychologists, and medics cleared prisoners for interrogation, advised and monitored abuse, falsified documents - including death certificates - and were largely silent as the scandal unfolded. This updated and expanded paperback edition gives newly uncovered details about the policies that engage clinicians in torture. It discusses the ongoing furor over psychologists' participating in interrogations. Most explosively this new edition shows how interrogation psychologists may have moved from information-gathering to coercive experiments, warning all of us about a new direction in U.S. policy and military medicine - a direction that not so long ago was unthinkable.
