Yet there is a central authority involved in this problem: the Fraternal Order of Police. It is that Fraternity that accepted, and made common, these "courtesy cards" as a way of business. The corruptive rot clearly has centralizing forces. The FOP and the police unions have the ability to combat them centrally and presumably enforce a higher standard of behavior, if they wanted to, just as they had a hand in creating the corruptions in the first place. If they wanted to fight it (they probably don't).
