Film Review: S21 - The Khmer Rouge Killing Machine
They did interviews with many guards and torturers as well as a few detainees who ended up living. The most bizarre thing was how these normal people could become so cold and ruthless. Some spoke about the US fighting in Cambodia in the early 1970s and the need for what he saw as patriotic fighters so they fought. What was interesting about it was the manner in which the US helped motivate the push for the communist government of the Khmer Rouge by invading. Moderate citizens saw an opportunity to fight for their own sovereignty. They then became indoctrinated with fear - everyone became a spy who spied on everyone but themselves.
The survivors discussed the difference between 'destroying' and 'killing'. The Khmer Rouge killed 2 million people.
