New York City Mayor Rudolph Giuliani bans any photography or video recording at the Ground Zero wreckage zone of the WTC collapses unless authorized by the police commissioner, claiming this is because it is a crime scene. Signs warn the public of a class-B misdemeanor and police keep the press away from the site. [Associated Press, 9/26/2001] It is unclear how long the ban lasts, but it seems to continue into 2002 (see From September 25, 2001 to Summer 2002).
