If there is no good cops then what we have is an armed gang going around robbing and shooting people on the street. Violence has always been considered an OK solution to that. Of course, one would hope that the idea that there exists no good cops to arrest the bad cops is as absurd as it sounds. When you take a look though, you'll quickly realise that internally the good cops are the "bad apples". To be fair, this is all probably just the natural outcome of how police departments are built. Putting people in these positions of power with no system built to effectively scrutinise their actions is inevitably going to lead to large scale corruption.
