Why was Phat, the Khmer Rouge leader, killed?
In the movie, it can be noted that Phat (played by Monirak Sisowath) was the leader of the section of the camp Dith Pran had been in. Realizing that Pran was an intellectual and thus not a brainwashed slave of the Khmer rouge, he puts his trust in Pran to look after his unnamed son (Lambool Dtangpaibool). When Phat witnesses a group of Khmer soldiers mercilessly shooting innocent civilians, he hands his son to Pran and tells him that he must "stop the killing". later, an alteraction between Phat and the troops are shown, with dialogue that remained untranslated and indecipherable. Phat is then immediately shot by one of the Khmer troops and his body left to rot in the open as the Khmer quickly escape and leave camp. I've always wondered in my heart WHY he was shot, simply for arguing with the soldiers? And if he was in a position of authority as a camp leader, why would he get shot by his own troops?
On a side note, I do wonder whatever happened to the actors who played Phat and his son - I notice in imdb that the "Killing Fields" was pretty much the only film they had a role in. If that is true, I find that sad, as they were a major part of the film and seemed quite overshadowed into obscurity.
