Security ... think about it!
Most of the security will be found on the ground: 64 different agencies, more than 1000 officers, and a whole range of hardware from armored vehicles, to bomb dogs and radiation sniffers. Homeland Security Secretary Janet Napolitano says there is no credible threat against the Super Bowl. But, it's an obvious target and the recent attempted bombing of Northwest Flight 253 is a warning that al Qaeda is intent on hitting the U.S. "It really awakened people to the fact that al Qaeda is a really persistent threat," Napolitano said. "There are individuals actually within the United States who adhere to those beliefs to the point of violence."
