Hong Kong was supposed to be free to control itself until 2048, democracy and free speech etc. China the decided that Hong Kong was starting to getting a little too free and started to tell the sitting president to shut the protests down.
China eventually took back control and instituted a national security law that could be used for pretty much anything after the crackdown didn’t quell the unrest.
I was actively following it live as it unfolded. It was very sad to see how much young people fought for basic freedoms and still lost it.
I remember being torn between my general non-violence stance and also understanding the protestors reciprocating the police violence.
