There is also the union and the PBA which is their real strength. They handle media propaganda and political donations

Most of the time they don’t really have to. Because they are invariably found not guilty on reason of that they were a cop, and have privilege. So they sue, get their backpay plus money for mental anguish, pain and suffering. If they reach a deal with the town to keep their benefits they just go to another town and get a new job there.

In most places charges are delayed so cops can retire and not lose benefits.
