It's estimated that more than 1 million Uyghur Muslims have been detained in camps in China, where they may be subjected to forced labor, sexual violence, torture, and religious restrictions. Today, we explore two nonfiction books that help understand the crisis. First, Geoffrey Cain speaks to Scott Tong on Here and Now about his book The Perfect Police State, an overview of the surveillance technology China is employing to monitor Uyghurs. Then, Nury Turkel speaks to Ayesha Roscoe on Weekend Edition Sunday about his book No Escape, an investigation into these torture camps and the life of Uyghur refugees.
