So-called professional courtesy is the canary in the coal mine. If there's a jurisdiction where police officers can speed with utter impunity, it's a good bet that a lot worse is going on.

In my own city, I was appalled by the spectacle of hundreds of police officers protesting in and around a courthouse where officers and union officials involved in a ticket fixing ring were being arraigned.
