The top law and order body has ordered a crackdown on discipline in the mainland's unruly police force. Three decrees have been issued forbidding officers from accepting favours from suspects, extracting confessions by torture and bullying complainants. In addition, the Central Committee of Political Science and Law will launch a re-education campaign in the first half of the year for the rank and file. Cases of officers acting above the law were highlighted by the conviction of policeman Zhang Jinzhu in Zhengzhou, Henan province. Zhang reportedly killed a man and seriously injured another after driving while drunk. He was sentenced to death on a charge of manslaughter by Zhengzhou Intermediate People's Court. Committee secretary Ren Jianxin warned police officers that the three decrees had to be implemented. He also warned them to stop offering protection to entertainment facilities and illegal businesses. In addition, more forceful measures will be adopted to increase transparency in the force.
