BEIJING (AP) — China's deep-rooted practice of using torture to extract confessions from suspects has seen little improvement despite measures introduced since 2010 to reform the criminal justice system, an international human rights group said Thursday. Yet, despite regular accounts by victims, reports by international human rights groups and exposes in state media, Chinese authorities have insisted that the practice is waning. In June, Peter Humphrey, a British man convicted of illegally obtaining information and later released on medical grounds and deported from China, told the media that Chinese authorities withheld medical treatment for his prostate problems to pressure him to make a televised confession in 2013.
