S-21, also known as Tuol Sleng, is a converted school in Phnom Penh where the Khmer Rouge tortured and killed political prisoners.
There are hundreds of pictures on the walls. I didn’t visit S21 for my first four months living here. Now that I’ve lived here and assimilated a bit, the faces look just like the faces I see every day. Some of the photos like this one are very well done and life-like. It was gut wrenching to see this. Change the shirt and this could be any of the kids I pass every day on the street.
