Thousands of people died after being brutally tortured in S-21. How could this happen? How could such a place exist? How could people do this to each other? This book gives answers to these essential questions. Scientifically, but easily readable, it gives a unique insight in the Khmer Rouge’s main prison. This book tells the story of the inhumane treatment of prisoners and the people who treated them that way. By not only focussing on the victims, but also on the perpetrators it creates an understanding of the horrible things that happened. A whole system of killing and torture was established with forces greater than one could imagine. Meelker uncovered the systems in which normal people could commit the most brutal crimes in S-21. Would you do the same in such a situation?
