Good cops that do not fight against bad cops are by definition bad cops. If they allow the corruption without fighting it then they are guilty by association. The same goes for civilians who don't turn in murderers. The cops arrest them for being accessories to the crime. Just for knowing about a crime and not saying anything one can be an accessory. Why shouldn't we hold cops or government agents to their own standard?
