Police need tighter rules to govern behavior, experts say

Judicial specialists on Sunday called for more specific rules to govern police officers after a video showing an officer arguing with two women on May 21 raised a public outcry.

The video, which is around five minutes long, shows the uniformed officer in Shenzhen, Guangdong province, engaged in a loud - some say abusive - argument with the women.

The women were standing on the street when the officer drove up in an official car and demanded that they show him their identification cards. One of the women later said that the officer's check was apparently random.
