World's greatest city police force even greater than thought

The nation’s largest police department, with about 37,000 officers, has spent tens of millions of dollars – much it from federal grants – on an array of high-tech security measures designed to thwart threats potentially more daunting than another attack on a downtown skyscraper. It’s also assigned 1,000 officers to counterterrorism duty, including 10 detectives posted around the globe who collect and share intelligence.

Overall, it’s an effort unmatched by any other city in the nation, and perhaps the world.
