Anyone who wants to understand what went through the minds of the torturers, and comprehend how they could perpetuate their atrocities needs to read this deeply moving book. The grubbiness, the gangsterliness, the banality, the bureaucracy and the horror are conveyed in their true magnitude. Yet there is a detachment about it that adds to its credibility. This book is not about left or right, it condemns no political ideology, it doesn't blame the USA - it just tells us what happened and explores deeply how it could happen. I read this book and could not get its vivid presence out of my head for days. Like some psychological trauma, I needed to talk it over afterward.
