Violence is not good, I was a victim of police violence in HK when I went back 10 years ago.
But if you want to be an aggressive protester, and decided not to leave when the police asked and warned you to, and you still act as an aggressive protester, then you are just asking for it.
I feel HK government should really stand up against these trouble creators and at the same time give candies to calm and peaceful citizens.
That way HK government can gain better reputation than now.
These 刁民 is taking advantage of the current tension between government and citizens and create trouble and 屈 police. Of course, police always 屈 citizen as well, not surprised there.
