The World Organization to Investigate the Persecution of Falun Gong further called attention to portrayals of Wang Jindong on state-run television, claiming that the man who self-immolated on the square was not the same person who appeared in subsequent interviews with CCTV. It pointed to a voice analysis conducted by the Speech Processing Laboratory at National Taiwan University, which concluded that the voices did not match, and also noted that the hairline and facial proportions appeared to be different. These observations were used to advance the theory that the self-immolators were actors.
