That's the real issue, IMO. Having a bad apple is one thing, the real problem is the level of protection departments offer to their own "bad apples," to the point of complicity, so that you rarely see officers held accountable for their actions. Too often officers are permitted to act outside of the very laws they're entrusted to enforce.
In other words, of course you're going to have officers that are screw-ups, are incompetent, or they're just outright a-holes and have no business occupying a position of authority, but it's the failure of departments and their officers to take not only the initiative, but the responsibility, to see that such officers are not only held accountable for their mistakes and transgression, but are removed as quickly as possible.
