By the early 1990s, extremist Hutu propaganda had started to spread in newspapers and on the radio, radicalizing Rwandans. Over the course of just 100 days [in 1994], about 800,000 Rwandans, primarily Tutsi, were killed. On April 22, 1994, [Hussein] Longolongo recounted, he and an armed group of men entered a chapel where dozens of Tutsi were hiding. "We killed about 70 people," he said. "I was brainwashed." Eventually, more than 120,000 Hutu were arrested on charges of participating in the genocide. In prison, [Longolongo] was forced to take part in a government-sanctioned reeducation program. He initially dismissed much of what he heard. "But as time went on, I became convinced that what I did was not right," he told me. Longolongo also participated in more than 100 of what were known as gacaca trials. Gacacawhich roughly translates to "justice on the grass""had historically been used in Rwandan villages and communities to settle interpersonal and intercommunal conflicts. Now the government transformed the role of the gacaca court to handle allegations of genocide. Many survivors were initially reluctant. "They would say, 'How can you forgive those people?'" [Albert] Rutikanga told them that these conversations weren't something they should do for the perpetrators. "Forgiveness is a choice of healing yourself," he would say. "You cannot keep the anger and bitterness inside, because it will destroy you."
