Giuliani took down the mob by trapping them. The mafia is not what it used to be because of his great work. But I guess it would have been easier and less stressful to just put away a few low level mobsters, and not risk all kinds of fireworks by going after the big guns more forcefully than any big city mayor had ever done before
