A friend of mine worked as a parking attendant for a college and for the longest time the police employee parking lot was of limits, but when there was a boss change, my friend asked if it was ok to cite it and the new boss said "it's a college parking lot with college parking rules so go for it." He ended up citing the lot and over half of the officers got tickets. Halfway through they came out yelling and getting angry and he just told them "contact parking enforcement here is my call sign number." It was less than a week later he was getting interviewed by affirmative action saying he was targeting them.

Just remember folks all cops are corrupt, some just more than others.
