Other than an accident I can't think of any scenario where I would voluntarily have interaction with the police.You're advocating that the police be an all powerful organization....
I prefer to "Police" my own. Two idiots start attacking me, they gonna end up shot.
Problem solved.
No need for a government sanctioned thug in a costume, trying to exert authority over the general populace.
They're not your friends and they're not here to help.
