Not really
Conservative ‘protesters’ get treated with kid gloves, or pardoned by the governor of Texas. They usually don’t get charged. They have friends in the forces.
Progressive protestors get maced, shot, beat to shit, locked up, maybe charged but probably not since they are more frequently non violent, and then they maybe get a settlement.
E.g., how will this help those protesting cop city? The cops are already ignoring the law.
The courts absolutely do something. My point is that most of the damage is done before it reaches the court.
Cops don’t arrest cops or people on their team. But when they do, prosecutors don’t charge cops. Cops do arrest nonviolent protestors. Prosecutors do charge nonviolent protestors. Later those charges are dropped, or they’re set free with an agreement not to sue the department, or occasionally there’s a settlement, that taxes pay for.
