I agree that we should hold politicians (especially) and other public servants to a higher standard as well but they can't as easily detain you or search you and your property or shoot your 42 times for mistaking your orange safety wallet for a gun
Mind you, I actually think that most police are good but as the saying goes "one bad apple spoils the bunch... especially when the good apples shield the bad apple"
or maybe I have the saying wrong
or maybe I just like apples
