One man’s journey to the heart of the Killing Fields.The Khmer Rouge ran what is regarded as one of the twentieth century’s most brutal regimes. Yet the Killing Fields of Cambodia remain unexplained. Until now. In 'Enemies of the People' the men and women who perpetrated the massacres – from the foot-soldiers who slit throats to the party’s ideological leader, Nuon Chea aka Brother Number Two – break a 30-year silence to give testimony never before heard or seen. Unprecedented access from top to bottom of the Khmer Rouge has been achieved through a decade of work by one of Cambodia’s best investigative journalists, Thet Sambath.
