The deaf community has widely condemned the official sign-language interpreter at the Mandela memorial for being a fraud. Knowledgeable signers say the man had “zero percent accuracy” and that he flapped his arms without any purpose during President Obama’s speech. Experts agreed. “It was horrible, an absolute circus, really, really, bad,” an official interpreter said. Government officials have promised to investigate how a man with no relevant experience could have reached a position so close to some of the most powerful people in the world.
