Tens of thousands of people attended memorial services for Nelson Mandela across South Africa this week, including a crowd in Johannesburg that included celebrities and dignitaries from around the world. U.S. President Barack Obama shook hands with Cuba's Raul Castro at the memorial, a rare gesture between the leaders of two ideological opponents that reflected the anti-apartheid hero's spirit of reconciliation. But the peace and harmony did not stretch to South African President Jacob Zuma, whom the crowd at the rain-soaked FNB Stadium in Johannesburg booed and jeered as he prepared to give his closing address. There was also global attention thrust on Thamsanqa Jantjie, the sign language interpreter who was branded a fake and accused of gesticulating gibberish before a global audience of millions. It later transpired that Mr. Jantjie, who suffers from schizophrenia, was hallucinating that angels were entering the stadium while he was working on stage.
