Transcript for Super Bowl Security: Law Enforcement Deploying Latest Tech
Thanks very much. Counting down to the super bowl now. More security than ever this year. The latest technology is being deployed to counter possible attacks amid heightened concerns about threats from Isis, Al Qaeda and the lone wolves they inspire. Pierre Thomas is in Phoenix with the latest. Good morning, Pierre. Reporter: Good morning, George. The super bowl is supposed to be about fun and games but law enforcement is planning for every nightmare scenario. Those horrific attacks in France very much on the mind of authorities protecting this year's super bowl as thousands of fans pour in. In an exclusive interview inside the stadium, the homeland security secretary warned of a new stage in the fight against terrorism. More lone wolf style attacks. More smaller scale attacks. Our challenges in homeland security are evolving. We have more concerns about domestic-based acts of violence. Reporter: While he says there are no specific credible threats against this weekend's game, they're prepared to respond by any means necessary. This U.S. Customs black hawk helicopter part of a fleet of aircraft guarding the super bowl from above. The airspace is restricted so if an aircraft comes too close it's a job for this crew and others to escort it out. Also in the air fighter jets like the one I flew in last year. If they do not respond, they will use missiles to shoot them down. Law enforcement is now deploying the latest in technology, high-tech scanners to search every item comes into the stadium. What are you looking for? We're looking for any weapon, bombs, weapons of mass destruction. Reporter: Katy Perry's costume, everything gets checked out. Her stage came in and have the port ao-potties and paraphernalia, Jerseys, everything. Reporter: For the first time we see what it reveals and they're using x-rays to see everything. Look there, he's able to zero in and do close-ups hunting for any anomaly. Officers will be wearing portable radiation detectors and there will be bomb-sniffing dogs. Bottom line, police are taking no chances so everyone can have fun. Robin. Every precaution. All right, Pierre, thank you.
