New York is beefing up security for the World Trade Center site ahead of the 10th anniversary of the Sept. 11, 2001, terror attacks.
The lower Manhattan force will eventually rise to 670 larger than any of the 76 precincts in the five boroughs and entire police departments in other cities across the country.
The thousands of people expected to visit the Sept. 11 memorial after it opens this fall will endure airport-style screening and be watched by closed-circuit cameras as part of the attack site opens publicly for the first time since 2001.
