NEW YORK—The “extreme and unthinkable” suffering that the Chinese regime has inflicted on members of the faith group Falun Gong typifies Beijing’s totalitarian tactics, which, if left unstopped, could eventually come to the free world, cautioned human rights advocates on April 18. “The Chinese Communist Party thrives on the ignorance and apathy of people around the world,” said Alan Adler, chair of the New York-based Friends of Falun Gong. “While our backs are turned and our eyes closed, they take advantage of our weakness and do their evils unchecked.”
