Those four cops deserve far more sympathy than does Mike Huckabee.
I don't like cops, but they certainly do deserve more sympathy than a guy who lets rapists and murderers run free.
Of course it is even worse than the Willie Horton scandal that sabotaged Mike Dukakis: Willie Horton was only "furloughed" -- not released completely from legal supervision. Willie Horton was supposed to go back to a Massachusetts prison; Maurice Clemmons was simply a gigantic mistake. Unless one has severe questions about the guilt of a person one does not free a convicted criminal.
I have mixed feelings about cops; the power that a cop wields attracts the worst sort of people to wield such power. I can't imagine a more satisfying career (short of gangster or a financial fraud) for a sociopath.
