Yet despite such similarities, the terror-fighting approaches of New York and L.A., like the cities themselves, reflect very different traditions, styles, and, above all, resources. New York, which knows the price of failure and thus has a heightened “threat perception,” sets the gold standard for counterterrorism—and has the funding and manpower to do it. Kelly, 65, views his highest priority as ensuring that al-Qaida doesn’t hit the city again. “When your city has been attacked, the threat is always with you,” he tells me. Deploying its own informants, undercover terror-busters, and a small army of analysts, New York tries to locate and neutralize pockets of militancy even before potentially violent individuals can form radical cells—a “preventive” approach, as Kelly calls it, that is the most effective way that police departments, small or large, can help fight terror.
In L.A., a city that has never been attacked, terrorism is a less pressing concern than gang violence and other crime. Lacking the political incentive, and hence the resources, to wage his own war on terror, Bratton, 59, has instead pooled scarce funds, manpower, and information with federal and other agencies—an approach that federal officials hold up as a model for police departments that can’t afford New York’s investment.
