Security Office 21, or S21 is the former high school turned into a torture chamber by the Khmer Rouge. Babies, girls, boys, men, women--more than 20,000 enemies of the state were slaughtered here between 1975 and 1979. These people were treated with diabolical cruelty. Babies were ripped from their mothers' arms and bayoneted. These pictures are the silent witness of the dead, many thousands of whom perished here. It is now called the Genocide Museum. You really don't know what to say as you pass through here and imagine the anguish of these poor victims. Yet now, many young people are not much aware of the Khmer Rouge and tuk tuk drivers promote it as a tourist attraction "I take you to killing fields", just business for them.
