Not all police officers are bad folk. But here is the difference, the police, when the root out a bad one, will say "this is not representative of who we are" and "one bad apple....". However. It is against the law for a policeman not to come forward when they see an illegal act being performed by a fellow officer. So... either no one ever notices the behavior of those few "bad apples", in which case the police aren't very good at their job - that being the detection of illegal behavior, or they are aware. If they are aware and they are not speaking up, then they are actually all... bad apples.
