There's no reason to treat cops as second-class citizens. There's no evidence to suggest widespread power-abuse, despite all the FUD from BLM. Are there some bad apples? Sure, but there are bad apples in every profession and steps like that only punish good officers and make corrupt officers more careful when they perform misdeeds.
You cannot neuter the power of every profession of authority. All you're going to do is build instinctive and reflexive mistrust of anyone in authority before they've done anything wrong, just like the reflexive mistrust BLM has whenever anyone interacts with an African-American.
