JOHANNESBURG (AP) — A man who provided sign language interpretation on stage for Nelson Mandela's memorial service, attended by scores of heads of state, was a "fake," the national director of the Deaf Federation of South Africa said on Tuesday. The unidentified man seen around the world on television next to leaders including United States President Barack Obama "was moving his hands around but there was no meaning in what he used his hands for," Bruno Druchen, the federation's national director, told The Associated Press. The scandal over the interpreter is another indication of bad organization of the historic memorial service at a huge soccer stadium.
