Security officials are taking super-sized safety precautions ahead of this years Super Bowl.Homeland Security officials brought larger-than-life Vehicle and Cargo Inspection System machines into Indianapolis to help scan the countless semi-trucks that will make deliveries to Lucas Oil Stadium.A three-person crew, a high-tech sensor and a robotic arm work together to expose what possible offenders may want to hide from law enforcement officers, said David Karmin with Customs and Border Patrol."Our job is to safeguard the event, as well as the people coming to the city of Indianapolis for the Super Bowl, Karmin said.CPB Official Brian Bell said the mobile VACIS system can see through at least six inches of steel, RTV6's Rafael Sanchez reported.We can detect people, handguns and rifles, Bell said. "You'd be a fool to bring something into that stadium that you shouldn't. Were going to catch it. Our goal is to look at every vehicle that makes a delivery inside the stadium and inside the secure perimeter. We are looking for anything from explosives, to weapons, anything contrary to law.Officials said the VACIS machine can scan at least six semi-trucks within minutes, and they dont expect the security scans to delay other vehicles getting into Lucas Oil Stadium.Our goal is to ensure the safety of 150,000 people coming to Indianapolis and the stadium. We want to make sure they are safe," Bell said.
