The NFL says Tampa's Raymond James Stadium will be one of the safest places in the United States when the Super Bowl is played Sunday.
The FBI, Customs and Border Protection and numerous other federal agencies will assist local police in protecting players and fans.
Milton Ahlerich, the NFL's vice president for security, said at a news conference Monday that the heavy security for this year's game will be typical of every Super Bowl since the Sept. 11, 2001, terrorist attacks.
Officials declined to say how many total personnel will be involved. But at least 20 different federal agencies will be involved, handling duties ranging from protecting airspace to arresting people selling counterfeit merchandise.
