A police officer's job is keeping order, and they're paid by the state, not directly by taxpayers. So they're enforcers for whatever order the state decides works for them. If left-wing groups paid police officers to run long-term private security, and infiltrated law enforcement, and did all the stuff right-wing groups did, police officers might start espousing more left-wing takes on matters like treating protesters with respect as fellow citizens.

I don't like how things are, and I don't agree with right-wing groups. I'm pointing out a hard truth. I think it's great that people are out on the streets asking for what they want, and that more and more people are listening to them. But I'm pessimistic that anybody in power will enact meaningful change, because the protesters don't act by the laws of power. That will become ever more important, and the failings ever clearer, the more and more people in power respect only power and not substantive public policy.
