I've said it before, but it bears repeating.
A "police officer" is a person who commits the act of policing; of enforcing legislation for political bullies in exchange for stolen money. "Police" is not the person, it is the set of behaviors the person commits. This is why it isn't "collectivist" to admit there are no good cops.
It is utterly impossible for there to be such a thing as a "good cop". Good people do not commit the acts that fall under the description of what police do.
Police commit acts of legislation enforcement as the core, defining characteristic of being police. Just like rapists commit acts of rape as the act which makes them rapists. The label is all about the acts committed, not the people committing them. Do different things, be given a different label.
If you will lower yourself to commit those unethical acts, it doesn't matter if you save puppies, too. You are a bad guy. When you are acting as a "police officer" you are doing wrong, even if you help someone in the moment.
To be a police officer you demonstrate a lack of ethics by doing those acts which earn you the title. It is not collectivism to judge individuals by what they do rather than who they are.

I hope I add something you find valuable enough to support.
