Should we be surprised by Kerik's indictment? Kerik has always had thug written all over him, but the inclination to identify with the aggressor caused many to treat this showboating bully as if he were a good guy. That he was a police officer only attests to the fact that law enforcement agents and criminals are sometimes little more than different sides of the same psychological coin.
And, Kerik's pal Giuliani is another example of a guy who oozes thuggery. If we ignore this, we do so at our own peril. Giuliani gets a great deal of mileage out of his handling of crime in New York, but I suspect that even Stalinists weren't half bad at controlling street crime during their heyday.
