There has to be some coordination, if suddenly all the protests and antifa demonstrations stopped seemingly overnight in news reporting.

I would be surprised if interactions with police quite suddenly turned less confrontational. People still do things to attract police intervention and police still respond and have to leverage lethal force, but we don't hear that much about it in the media. so, what gives?

Police lethal force is still covered whenever it happens in my local paper.

The protest coverage faded out over time; anecdotally, so have the protests I've seen while driving around town.
