But the downside to Giuliani's make-New York-safe-and-clean campaign is the trigger-happy police force. Recently, an unarmed Guinean, Amadou Diallo, was shot 19 times. The killing has become a major national issue, with the Mayor's critics accusing him of giving the cops too free a rein. It could hurt him in his attempt to get elected as the Senator from New York. The present incumbent, former ambassador to India Daniel Patrick Moynihan, who has a serious drinking problem, has announced that he is stepping down. Giuliani's main rival for the seat? The First Lady, Hilary Clinton, though she has yet to officially confirm her candidacy.
