NYPD Heightens Security as 9/11 Anniversary Nears

Ahead of the 10th anniversary of the September 11, 2001, terror attacks, the NYPD is beefing up patrols at some locations throughout the city.

Police Commissioner Ray Kelly said there will be more uniformed and plainclothes officers at sensitive locations before, during and after the commemorations on Sunday — and that the extra security is in part a response to Osama bin Laden's threat to repeat an attack on the anniversary.

"That gives us additional concerns, and I think we're doing everything we can to protect the city," Kelly said, noting the threat was found in notes uncovered in May after bin Laden was killed in a raid by U.S. special forces in Pakistan.
