Have you watched any of the actual live streams?
Protestors day one were hurling heavy rocks tens of yards at riot police as they stood. They are constantly being dehumanized - the protestors stand inches away and scream at police. All of this during a pandemic, by the way.
It's obscene to watch the media (CNN in particular) repeatedly claim that these nationwide protests are peaceful, when the police are universally yelled at, belittled, threatened, and dehumanized while stoically standing, and almost all of these riots seem to be accompanied by late night looting. Not to mention, I've repeat fly witnessed protestors belittle police for being black, female, and/or physically small.
I'm not saying there aren't legitimate reasons for protestors to be angry, only pointing out that this notion that police are just antagonizing innocent, peaceful protestors is pure propaganda.
Aside: that I have access to 20 first person perspectives from all sides of a historic event in real time, from the comfort of my home, is a testament to how far humanity has come.
