Cops are mainly to suppress anybody who doesn't go along with the will of the powerful.

They don't exist to reduce harm to the many, they exist to protect the assets of the Owner class, which is why in Law property "crime" is usually more severely punished than anything but murder and why cops are vastly more speedy at investigating and prosecuting "crimes" committed against the Owner class or their Assets than they are when it's the riff-raff that suffers.

They're minions to a handful of people, not servants of the public.
