It's a question that's been posed to Bloomberg many times. "There are powers only governments can exercise, policies only governments can mandate and enforce, and results only governments can achieve," he once said. "To halt the worldwide epidemic of non-communicable diseases, governments at all levels must make healthy solutions the default social option. That is ultimately government's highest duty." It's a forthright answer: If the government can do something that makes people safer, it must. In fact, it has "no higher duty."

It's a philosophy a lot of liberals are happy to accept when applied to cigarettes, restaurant ingredients, and the like. But their tolerance for this mindset is inseparable from its darker manifestations. In the press, Bloomberg isn't nearly the bogeyman that Rudy Giuliani was during his stint as mayor, but that doesn't mean that his record on civil liberties and minority rights isn't deeply suspect. The New York Civil Liberties Union explains what is perhaps the most problematic policy of his tenure. "The police are stopping hundreds of thousands of law abiding New Yorkers every year, and the vast majority are black and Latino," the group notes on its "Stop and Frisk" issue page. "More than 4 million innocent New Yorkers were subjected to police stops and street interrogations from 2004 through 2011, and that black and Latino communities continue to be the overwhelming target of these tactics. Nearly nine out of 10 stopped-and-frisked New Yorkers have been completely innocent, according to the NYPD's own reports." It isn't every mayor that presides over the harassment of millions of innocent people.

More recently, it has come to light that the NYPD under Mayor Bloomberg has engaged in systematic, secret, illegal spying on many innocent citizens -- some of them outside the NYPD's jurisdiction! -- simply because they were Muslim Americans. That initiative, reminiscent of a police state, is more alarming and objectionable than the move to restrict salt and trans fats in the city. But the line separating those policies isn't nearly as clear as liberal paternalists want to believe.

Mayor Bloomberg isn't the kind of guy who asks himself, before taking action, "Does government have a right to do this?" Instead, he asks himself, "Is this going to make people safer?" That is the underlying logic of nannying, stop and frisk, and illegal spying on Muslims. Do I think it'll make New Yorkers safer? Then government must do it. It's a brand of "non-ideological pragmatism" better suited to Singapore than the United States, yet because it isn't implicated in the culture wars -- because both Republicans and Democrats are willing to transgress against minority rights so long as the people disproportionately affected are poor or black or Muslim -- Bloomberg is lauded for his spirit of centrism and reelected in America's flagship blue city. As one defender of Bloomberg and the New York police commissioner wrote to the New York Daily News, "War does not always make allowances of convenience. The Muslim community should be thankful that its members are not placed in internment camps. After all, they, too, are being protected from attack." What a pragmatic, ideology-free assessment!
