Why does the Police Film Civil Actions?

The Police films all the process of civil actions, marches and candle-lighting in commemoration of severely beaten Vahe Avetyan.
In an interview with Lurer.com officer of Department of Public Relations and Information Armen Malkhasyan, to the question for what purposes it’s done, he replied, “What’s the matter? 02 also films, is there anything wrong with it?”
To the observation of the reporter, whether it was done for 02, Malkhasyan stated that he meant that the Police press department also films, “They’re police officers, what’s wrong with it?” According to Malkhasyan the films aren’t used, they “are being filmed and if there are any social violations and etc, that’s another problem.”
