I agree with the idea of when you're following orders, you can not claim innocence or absolution from the wrongs of the institution giving the orders. Also we constantly see the police committing murder, assault, illegal search and seizure, human rights violations, accessory to all the aforementioned crimes and rico law violations by participating in a criminal enterprise through their"blue shield of silence" policy. However, if we say and repeat that ALL police are bad no matter what they do individually, we are actually punishing any good behavior by saying it will not be counted or acknowledged. If the few police who stick their neck out to report and get rid of corruption in their offices are not only met with torment from other police for crossing the blue line but are also met with the same from the public because nothing they do can ever be good, this will only make the police worse. It will contribute to making the police force an environment that is only desirable to the most corrupt people who couldn't care less about how they are perceived anyway. When the public attitude toward police is abject hatred regardless of their actions, this discourages people who may want to join to help clean up the police force because they don't want to become hated by their friends, family and society in general.
