NFL to review Boston Marathon bombings to plan for Super Bowl

NEWARK -- The NFL plans to take what investigators learn in the aftermath of the Boston Marathon bombings and incorporate it into its security plans for the cold-weather Super Bowl at MetLife Stadium.

The league said Tuesday that it has raised its security levels for all its games and events since the Sept. 11 terrorist attacks in 2001. For the past two years, it has worked closely with federal, state and municipal agencies to develop a comprehensive security plan for this Super Bowl, which will be played in the shadow of Manhattan.

The Department of Homeland Security has designated the Super Bowl as a Level One National Security Event for the past decade. More than 50 federal, state and municipal law enforcement, public safety, and emergency management agencies are expected to contribute to the effort, including state police in New York and New Jersey.

There also is an annual force of 4,000 private security and crowd management personnel. Only people with tickets or credentials are allowed within the 300-foot security perimeter around the stadium.
