The Police Force is an example of what happens when you give a group of people a load of power, but also institutionalise bigotry; they fear subsections of the population, who fear them in return, creating a toxic environment, which can only be resolved by reform of the police.

The problem is that the police see such reforms as an attack on their fellow officers, and therefore, as you said, circle the wagons and close ranks, with whistleblowers and Internal Affairs being ostracised by the rest of the Force.
