I live in Hong Kong right now and for a few months the protests did turn violent. I would say it would be equivalent to Minneapolis day 2 (but not day 3) where rioting and looting starts.
Past month's protests were slightly less severe. Slightly.
This video is marked by youtube as "offencive?". I mean there is scenes of the riots, but the community surrounding this channel is pretty upset about yt marking this as offencive. The community still thinks that yt is just siding with the chinese goverment. I think that the blood and riot scenes are not really much of a deal. You still see those in games and yt dosnt give a damn.
