I could not detect the presence of any cops in this incident, only that of a minimum wage security guard. Do such wannabe's regularly try and exercise authority inappropriately? You bet. Most of the real cops I know are overwhelmingly conservative AND republican.
Up here in KY, we are kind of the exception - more than half of the police forces, state, county, and local, are National Guard MP's as well.
But at the state and local level, KY is a Democrat stronghold; we just have the habit of sending Republicans to DC.
