"Tens Of thousands slaughtered for their organs in china, says new film"
Daily Mail interviewed the director of Hard To Believe, Ken Stone, and one of the participants in the film, Ethan Gutmann, an investigative journalist and China analyst. Ken said, "What drew me to the story was that the evidence was so strong and yet it's hardly talked about." "There's a general tendency to not want to look atrocities in the face," Gutmann told MailOnline. "We acknowledge a terrible atrocity only after it's over. Look at how long it took before the Holocaust was recognized."
