We need the police. Police need us.
I tend to agree.
But... That means cops cannot allow themselves to be used as cash eating predators by politicians. Nor can they administer extra judicial punishment. Nor can the see the Bill of Rights as something to be feared and gamed.
I could go on and on... No knock raids should be a distasteful footnotes in history books we teach in elementary school as the bad old days. Respect for private property and for citizens goes a long way to heal the problems we have.
