Some police officers said on Wednesday that new rules allowing members of the public to record the behavior of on-duty officers will serve as a constant reminder not to abuse power. But others were concerned about their identities being exposed during undercover work.

On Tuesday, the Ministry of Public Security started a training program for officers around China. It features a 70-minute video showing the correct way to handle different situations in close contact with the public.

The detailed new protocols said officers shouldn't prevent the public from recording their behavior if the filming does not interfere with them. They are also not allowed to grab video devices and delete footage.
