I wouldn’t be so sure about that. I used to live in the Collin County area. It is a north Dallas suburb and deeply conservative. The city police in those towns are nothing more than revenue generators. They write speeding tickets 24/7, but haven’t solved a significant crime in years.

I work on the nicer side of town - lots of police hiding in the bushes (literally, on motorcycles behind the sidewalk and in the bushes) with a RADAR gun and ticket pad.
I have never seen the motorcycle cops in the bad part of town, where the crime happens.
