I think one point that the last two years has nailed home (around the world) is that how protestors are treated has little to do with what their tactics and behavior are, and more to do with simply whether their message ideologically aligns with the police.

If the police agree with some group of protestors, then they're treated with kid gloves, and can get away with anything. The police will throw their hands up and say "nope, can't possibly enforce the law anymore, so sorry!" and stand back. If the police do not agree with some other group of protestors, they're going to get beaten, pepper sprayed, and shot with rubber bullets, no matter how they behave. All of a sudden, enforcement is no problem.

Things I’ve seen this year.

People who Molotov cocktailed a police van with people inside. Let off with probation.

Police beat an unconscious person until they died. Internal investigation cleared them of wrongdoing.

It definitely matters what the protest is supporting/fighting.

Portland Police Department is just one particularly egregious example. Numerous leaked text messages between officers and the Proud Boys. Letting them know to take cover before tear gas is deployed and that they'll be told when it's "all clear" to come back out, letting them know that though some of their leaders have active warrants for arrest, that they are clear to come to the protest because there's no "other agencies" involved in enforcement, so there's no risk.

My example #1 was a BLM protestor, #2 was at the capital protest.
