With the Super Bowl fast approaching, the U.S. Department of Homeland Security is working hard to protect the waterways in Jacksonville, Fla.
Zackary Mann of U.S. Customs and Boarder Protection told a local news station, "The biggest challenge is that the stadium is surrounded by water."
The increasing number of boats, yachts and cruise ships now navigating the river adds to law enforcement’s concern over security issues. That’s why Homeland Security crews are using a heat sensor system on their boats as they patrol the waters.
Customs Officer Mike Gray said the equipment is being used specifically for Super Bowl security. "You can detect weapons and movement of people up to five miles away," Gray explained.
During Sunday’s game, security restrictions will keep most boaters at least 75 feet away from the river’s north bank.
