Who is rioter?

From June to first week of December 2019, police had fired over 10000 canisters of tear gas at protesters in Hong Kong.  Police not only fired tear gas at the area where protest carried out, but also to private and even residential area.

 

As a Hong Konger living in London, <Who is rioter?> to reveal my feeling towards the recent situation in Hong Kong.
