Wait until you read about the forced confession extraction in S-21 / Tuol Sleng...
Maybe my initial comment should be that this is taken out from [a book] that both Orwell, and the Khmer Rouge has read; which book would this be?
Also, confessions include names which extend the inquisition. It's the same thing the Indonesians did when exterminating communists in 65-66, or South Korea did during the Bodo League massacre, or Chile under Pinochet, or Guatemala when slaughtering the Maya.
You're not opposed to justice are you?
