On the Front Line in the War on Terrorism

Cops in New York and Los Angeles offer America two models for preventing another 9/11.
Three time zones, 3,000 miles, and a cultural galaxy apart, New York and Los Angeles face a common threat: along with Washington, D.C., they’re the chief American targets of Islamic terror. And both cities boast top cops, sometime rivals—the cities are fiercely competitive—who know that ensuring that a dog doesn’t bark will determine their legacies. After investing millions of dollars in homeland security, Police Commissioner Raymond W. Kelly of New York and Chief William J. Bratton of L.A. can both claim counterterror successes. What can we learn from their approaches? And will they be able to continue preventing terrorist attacks in their cities?
On the face of it, the nation’s two biggest metropolitan forces seem to have adopted kindred counterterrorism strategies. Both have roving SWAT or “Emergency Service Unit” teams, equipped with gas masks and antidotes to chemical and biological agents. Both have set up “fusion” centers to screen threats and monitor secret intelligence and “open-source” information, including radical Internet sites, and both have started programs to identify and protect likely targets. Both have tried to integrate private security experts into their work. Both conduct surveillance that would have been legally questionable before September 11. Both have sought to enlist support from mainstream Muslims and have encouraged various private firms to report suspicious activity.
