I’m fortunate that my police chief demands his officers be respectful and polite to everyone. We had two officers that were know for basically being bullies and they where removed shortly after he took command.
The result? You will still get a speeding ticket and such if deserved, but they are approachable and friendly. And when they pull up to the house (one neighbor complains all the time about everyone else’s dogs, but not his own) we have a nice chat.
