In Cambodia, between 1975 and 1979, some two million people died at the hands of the Khmer Rouge. Twenty years later, nobody had been held accountable. Haunted by an image of Comrade Duch, Pol Pot's chief executioner, photographer Nic Dunlop set out to bring him to account. The result of his journey, The Lost Executioner is an unforgettable, illuminating document that, by bearing witness, reminds us that if we ever turn our backs on genocide, we must accept a collective guilt.
