Security planning for Super Bowl XLVI began when last year's game ended.
Just a day until the Super Bowl, security is in full force at Lucas Oil Stadium and it is tighter than ever this year.
"We're looking for explosives, weapons, chemicals agents, even people inside vehicles," says Customs and Border Protection Officer, Brian Bell. "Everything from a personal vehicle to hot dog buns, to the Vince Lombardi Trophy, has to come through us."
Bell adds that the planning for security at this year's event began before the kickoff of last season's Super Bowl.
This weekend each officer will be carrying a radiation detector. Futhermore, a giant x-ray machine has been set up to scan every vehicle in addition to using dogs to sniff vehicles to sniff out explosives.
On the streets, police cameras are scanning the crowd using facial recognition software in order to look for known terrorists.
Software developed by the secret service provides personnel the best evacuation route from every seat.
"We can tell you exactly how long it's going to take to get you out of the stadium," says Indianapolis Public Safety Director, Dr. Frank Straub.
Considering a no-fly zone will also be enforced during Sunday's game, it shows how serious authorities are when it comes to keeping everyone safe during at America's favorite game.
