@Ron There was some fun dancing at protests in Newark, NJ. There's an established protest movement in the city and they have a positive relationship with the police department. Without masses of warriors in riot gear, things have stayed calm:

The mayor probably told the police that we know for a fact that the reason why all these other cities were escalating was because of police violence. The police are so aggressive with the protests, who reciprocate an act of violence, and then it’s on, you know? The police are familiar with the People’s Organization for Progress. We’ve had numerous marches were the police got accustomed to us. They didn’t really feel the need to have that kind of aggressive behavior that police usually have. And we also have a city administration, the mayor of which has an official policy that is anti-police brutality.

The difference in police tactics on the two sides of the Hudson River is shocking. And the results speak for themselves. When the police don't escalate, the protesters keep the peace:

But I saw on Instagram, that when we were on Broad Street, there was a guy with a baseball bat looking into the Dunkin Donuts, and looking like he was about to bash the window. I saw protesters rush over to him and move him away from the window. It wasn’t the police. It was a group of young protesters. Not no old people like me.
