Port Authority to add police at airports, WTC site

Osama bin Laden is dead, and spontaneous celebrations have been erupting everywhere, including at last night’s Phillies game.

But the news is also cause for caution.

The Port Authority says that “out of an abundance of caution,” it will add more police at its facilities including the New York area’s airports, the George Washington bridge and the World Trade Center site.

The Port Authority made the announcement early today, hours after the U.S. said Osama bin Laden had been killed. It says the extra police is not a response to any current threat and that all its facilities will operate normally otherwise.

Also, New York Police Commissioner Ray Kelly has issued a message to all police commands reminding them that while there’s no information indicating a specific threat to the nation’s biggest city, officers should remain alert.
