Book excerpt: history of sanctioned psychological torture techniques, say the experts behind this book. Having reached a joint crescendo of intolerance and horror, scholars from across the nation met in 2006 for a conference on psychological torture and what can be done to stop the practice. They agree with Alberto Mora, the U.S. Navy's general counsel, who fought to stop the Pentagon-sanctioned psychological torture at Guantanamo. Cruelty disfigures our national character. Where cruelty exists, law does not, Mora said. This book is the joint effort of those scholars, from the University of California Center for the Study of Human Rights in the Americas, to Harvard Medical School, to paint a clear picture of psychological torture, its long term affects, and spur action to stop the practice. The distinctly American form of psychological torture has four characteristics that make it attractive to the CIA and other supporters, say the authors.
