@Chaoran Liu (via Facebook) said: democracy and freedom is such a good excuse so rioting, blocking roads, setting fire, throwing petrol bomb at police or beating up innocent pass byers who simply disagrees with their way of protest got justified. There are many meaningful protests happen in the US every year asking for social equality and fairness, however why the US police suppress those movements but rather let them go to block roads or storm the capitol hill? People do have the freedom to protest but people also have the freedom to live peacefully and work freely.
