Political and security systems in Cambodia under the rule of the Khmer Rouge (1975-79):

The political and security systems in Cambodia under the rule of the Khmer Rouge in the years 1975 to 1979 include: Arrests, imprisonments, interrogations, torture, and executions:

Cambodians who were suspected of being enemies were arrested, tortured, and then executed by the Khmer Rouge under their regime. People who were suspected to be ‘’enemies’’ were executed.
Those who were convicted of treason were taken to a top-secret prison called S-21 where the prisoners were rarely given food, and as a result, many people died of starvation. Most prisoners died from the severe physical mutilation that was caused by torture.  Of the estimated 15,000 to 30,000 prisoners, only seven prisoners survived and under the DK control, 500,000 people were killed of whom were against the Khmer Rouge.
 Examples of the Khmer Rouge torture methods can be seen at the Tuol Sleng Genocide Museum. The Tuol Sleng Museum of Genocide is a former high school building, which was transformed into a torture, interrogation and execution center between 1976 and 1979.
