Internet police in 50 Chinese localities, including Beijing and Shanghai, launched a campaign to clean up popular social networking platforms such as Sina Weibo and WeChat starting Monday, in a bid to further curb cyber crimes. Their job includes detecting and removing illegal and harmful contents on the Internet, especially those harmful to children and women. Comments:

The Internet police are neither obliged nor supposed to make moral and political judgments on law-abiding online posts. It is only the illegal comments that have to be regulated. In a modern society, virtual or real, the police are part of the rule of law. Such being the case, online opinion leaders should not be an exception.

Making public their investigation and enforcement of the Internet regulations, China's cyber police are hoping to inject a stronger sense of responsibility into more netizens who are encouraged to report online misdeeds. Such a mode of police supervision is conducive to the benign interactions between the police and public in cyberspace, where all should resort to self-discipline and abide by the law.

Being a central part of modern society, cyberspace must not be allowed to descend into a lawless realm. The Internet police are real police officers fighting against crimes on a virtual battlefield. Thus they have to have the full support of netizens to fulfill their responsibilities and let the online public have a bigger say in their job.
