Reducation Camp in a Seminar Form
I used to rent a house from the retired warden of Cook Som Kay, which is kind of famous being the big jail of the capital city. It was a very pleasant and modest house, the yard was walled and we had a jackfruit tree. Our kids were small and it was a quiet single story residence off the street behind other houses. Our only neighbor was the warden and his wife who used to putter in the garden and feed the chickens.
Just after the war the jail held over a thousand people at a time, terribly over crowded, mostly awaiting processing before being shipped to other destinations. My grandfather in law was sent to "boy island" in the reservoir a couple hours north of the capital. There is also a "girl island". The two islands used to be for short term residents, young hipsters from the capital whose hair was too long or worked in hotels or bars, etc.
All members of the armed forces or civil servants were sent to "seminar camps" a euphemism for re education, or hard labor. Thirty to fifty thousand people were sent to the camps, there are no official numbers. At first people were dying like flies. Extreme malnutrition made people especially vulnerable to malaria. Higher level officials were sent to worse camps. The royal family and a few other high officials were sent to a camp that only had one survivor. The Lao are a Buddhist people and it's much easier to allow people to die than to kill them.
Most people were released after ten or fifteen years. It's not known how many died, a lot. If you look in Wiki under "concentration camp" you'll find a long list of countries and the types of camps. No mention of Laos.
Even today there are political prisoners, though few. Pro Democracy types from the late 90s and some religious folks, who knows. There is no free press, best not to make trouble. People still die from lack of medicine and food.
