22 SEPTEMBER 2011 - NEW YORK, NY: A recovery worker wears a dust filter while tourists look at the wreckage of the World Trade Center from a vantage point on Broadway in lower Manhattan near "Ground Zero" of the World Trade Center complex after the WTC terrorist attack, Sept. 22, 2001. More than 2,900 people were killed when terrorists crashed two airliners into the towers on Sept. 11, 2001. The site has turned into a macabre tourist attraction and the crowds are creating problems for law enforcement and recovery workers.   PHOTO BY JACK KURTZ
