The anthropologist Yan Yunxiang examined twenty-six cases of Good Samaritans who had been the victims of extortion in China, and he found that, in every instance, the local police and the courts treated the helpers as guilty until proven innocent. In none of the twenty-six cases was the extortionist ever required to provide a witness to back up the accusation; nor was the extortionist ever punished, even after the helper was found to be falsely accused.
