I think most of what you’re saying is not controversial, but I think you’re missing a lot of context. Those officers, and the protestors, exist in a country that still treats black people as second-class citizens in a variety of ways. Hell, the current President spent years saying the previous (black) President was illegitimate.

You want to see the protesters and officers as equal, but they’re not - the protesters are trying to change the status quo, the officers by and large want it to stay the way it is, and often want to make things worse for minorities (“Make America Great Again”).

Sympathy for the officers is fine, but remember they can quit whenever they want. Black people can’t quit being black.
