To Protect and Serve? Protect who?

I hate the American pre-occupation with the idea that police keep you safe. It's called the justice system because it provides justice not safety. What's the difference you ask. If someone commits a violent crime and is tried and punished, that is justice. If someone is doing something that you don't approve of and you have the police arrest that person in the name of public safety, that is tyranny. Police are a based on a quaint notion that you can put some citizens in government uniforms and supposedly give them powers that normal citizens don't have. The idea that this is a government by the people, of the people and for the people implies that it operates through the consent of the governed. You cannot give through consent a power you do not have. You cannot preemptively stop a crime from happening. If you saw a crime about to happen and ran and tackled the guy it would be you being charged with assault. So why should we think that the police would be enabled with a power normal citizens do not possess? Police ony ''protect" the populace by apprehending criminals, which by definition means they must have already committed a crime. Why does it take a police force to do this? Couldn't this function of the justice system be handled by private detectives and bounty hunters working towards collecting a fee. Why is it more fair to have a civil servant perform the task of a glorified go-fer? The common task performed by today’s police is mainly social control tasks based on moralistic laws not actual justice. Is breaking the speed limit really a crime? What about smoking a joint and then eating 4 Twinkies. Yes, that must be a crime against say, good taste? No, these are not actions that violate another citizens rights and are not crimes. The state should not be given the assumptive power to claim a violation against the public good. The public is a straw man that is comprised of individuals. Only individuals have rights. Certainly, post suggested speeds for roads and if someone is driving in a reckless manner and causes an accident, THEN you can hit them with a book as thick as you can get it. That's the line in the sand. Once they have committed an actual crime by violating a citizens rights the justice system needs to be there and fully enabled to deal with societies undesirables. But please, let’s do away with the notion that police can actually protect society from the very individuals that comprise it.
