In 1994, over eight hundred thousand Tutsis and moderate Hutus were hacked, shot, burned, and clubbed to death in the space of three months. Among the architects of this abattoir was a Georges Ruggiu, the only foreigner ever hauled before the UN court for his part in the genocidal Rwandan hate. He sat behind a microphone at what the world soon learned to call “hate radio,” a cacodemonic little radio station that spent its days spraying incitement like cheap pesticide: names, addresses, instructions, the daily worship of extermination. While the machetes rose and fell outside, he spoke in calm, professional tones, as if reading the weather or the football scores. Kill them. Kill them all. They are cockroaches. They are snakes.
