I got this off their infamus "What is a RealCop"
Real Cops drive with their windows rolled down, rain or shine. They write citations for 15 over the limit.
They don't stop cars with burnt-out license plate lamps; they stop them for exhibition of speed, vehicular
manslaughter, and drunk driving. Real Cops work radar out of the car, standing in the number one lane.
They hold the radar unit in a two-handed combat stance and flag down the offenders. A driver always
stops for a Real Cop.
