I went to Cambodia in 2005 coming from Thailand and going to Vietnam.
I and my driver did the tour backwards. I went to the “Killing Fields” first and then the S-21 Prison.
The Killing Field is just a plot of farmland outside of Phnom Penh. So many people were murdered here that there are bits of bones laying on the ground like twigs. Literally. The government built a 100 foot stupa in the middle of the park filled with human skulls. You can (and I did) opened the glass case and picked a skull up and looked at it.
The high school turned into a prison was a nightmare too. The Khmer Rouge hired brainwashed kids to do the torturing in the camp, and that the camp processed and murdered most anybody, including innocent women and children. There are mugshots of kids kindergarten age and younger. It was so sad.
The people that they targeted was anyone with any connection to a foreign country. if you were a foreigner, you were dead. (there was a picture of an Australian who was killed in the Killing Field, there were also some other foreigners who were caught by their navy and executed also.) People with an education were targeted. People with glasses were killed because they thought they were intellectual. I think it just devolved into someone being taken in that prison because somebody’s friend of a friend of a friend was a member of the old government.
Personally, I think the idea was just to cause a genocide of all the people except for a select group of adolescents who they could brainwash into their thinking. The government also let it be known that your life isn’t worth anything to them and that it can be easily taken from them.
There are landmines all over Cambodia, and it is easy to find someone without a limb begging on the street because they are useless for farm or other work. These landmines, and thus the Khmer Rouge are still killing people in the 21st Century.
Cambodia reminds me of an adult who was horribly beaten and mistreated as a child, and that there is a trauma that cannot be escaped. I once saw a news story recently of perverts going to Cambodia to have sex with children, as in 6 year old kids. They had an undercover camera and when all those babies ran out to greet, it made me so, so sad.
I am happy I went to Cambodia, but I was ready to get out. Phnom Penh was a creepy place and I did not 100% feel safe there. When I got to Vietnam, it was like returning to civilization.
As a side note, Duch is Chinese/Cambodian. He’s not ethnic Khmer.
