The last good cop was called Serpico. Look what happened to him. If you're a good cop and you don't turn in a bad cop, then you're a bad cop. And looking at all these departments there's many bad cops that the good cops don't turn in.. I guess that's the blue wall of silence so you're a bad cop, it's the truth. Every occupation has bad people and the good people try and eliminate them not protect them.. like I said serpico the last good cop!
