I have several police officers in my extended family and some who were old friends, classmates, etc...probably a dozen or more that I have known at one time or another.
They run a perfect bell curve of the good cop/bad cop chart. My wifes cousin is now a Federal Marshall and I trust him completely and he is a credit to his profession and a shining example to all. His brother also became a cop and was fired for gross misconduct, the final straw being a fist fight between himself and another officer on duty in uniform. I had a cousin who was so corrupt (we all knew it, it was obvious) that after he was arrested it is believed he was beaten to death by fellow officers to keep from implicating them. I have an old musician band mate that is now CHP in California who is also a shining example of a great cop who does his job admirably.
Like anyone else there are good ones and bad ones and most are right square in the middle doing their jobs and going about their business...just like every single profession in the world. Hats off to all who have worn a badge and tried to keep us loonies in line.
