Security stepped up at Super Bowl

Security measures at this year's Super Bowl have been stepped up following the recent attempted Christmas airline terror attack.

The increased security presence will include devices to detect both biological and chemical threats as well as 100 magnetometers and bomb-sniffing dogs.

The skies of Miami will also be protected during game day by Air Force F-16s, which will be on patrol, and a 100 yard buffer zone will be extended around the game's stadium.

The FBI will also run the Joint Operations Center, which utilizes 68 federal, state and local agencies and more than 200 representatives for threat response.

A separate Fusion Center will be run by the Miami-Dade Police Department to disseminate intelligence and other information to other South Florida police and government agencies.

"We collect intelligence from all over the world and then we disseminate it, so that everyone knows what's going on," William Maddalena, a Miami FBI official in charge of special events, told The Washington Post. "We'll have daily briefings to put out the latest information we have."

The intelligence, however, would not uncover the so-called "lone wolf" - one person acting alone to attack or disrupt the game.

"They operate by themselves," John Gillies, the special agent in charge of the FBI's Miami field office, told the Washington Post. "They operate in seclusion. They don't discuss their plans or potential threats to anyone else."

No viable threat has been made against the Super Bowl, but security will remain higher than usual.
