On February 19, 2024, the committee and teachers of the American Intercon School led 12th graders to the Tuol Sleng Genocide Museum for the purpose of allowing students to learn about the history of this museum. The former Security Department 21 (S-21) of Democratic Kampuchea was led by Pol Pot (known as Saloth Sar) on April 17, 1975. ​ This museum was a place of detention, interrogation, brutal torture, and execution for the accused of being foreign spies. ​​ On January 7, 1979, the government fought the Pol Pot regime and collected many different pieces of evidence for S-21, such as photographs, films, confessions of victims, torture equipment, handcuffs, and the bodies of 14 victims. These important documents were exhibited to national and international guests to witness the brutality of the regime. The Tuol Sleng Museum of Genocide opened on the same day that the Cambodian People’s Revolutionary Court began the trial against the top leaders of Democratic Kampuchea, including Pol Pot, Ieng Sary, and Khieu Samphan (August 19, 1979). ​During this study tour, all the students learned about the Pol Pot regime, the massacre, as well as witnessed the acts of torture, murder and other statues kept as evidence in the museum. ​Therefore, it is very important that we protect this place, especially the documents and evidence, to confirm and bear in mind the oppressive acts of the Democratic Kampuchea regime and not to allow this regime to return to Cambodian society again.
