I agree. Police are unnecessary in most municipalities. The efforts of armed property owners and the local sheriff are plenty to keep order and prevent serious crime.
Ask yourselves: what would change in my neighborhood if the police just went away? Chances are the answer is “not much”. The police do not keep crooks from breaking into your home or business; you do that. The police do not keep crooks from robbing, raping, or mugging you in the street; you do that. The police do not keep crooks from stealing your car or bicycle or busting into your business; you (and private security guards) do that. Are you going to stop doing that just because the Boys in Blue aren’t there anymore? Of course not.
One thing that would change: you’d know that the guy beating you up or putting a bullet into you wasn’t going to use a badge to get away with it.
America got along fine for almost 150 years without professional police. We can do so again.
Paying for schools is mandated, you have to do it. Police, fire, ambulance, etc., are optional so they are the first to go. In a perfect world you could fire 90% of the worthless teachers and keep the police.
But who will offices and grocery stores hire to stop traffic for them and their customers?
