BELL BUCKLE, Tenn. - If you live south of Nashville and you're hearing explosions, the Federal Bureau of Investigation is blowing up cars and tractor trailers in Bedford County. But, it's only for practice.
The explosions are part of a unique school for bomb squads.
The bomb squad technicians from police departments all over Tennessee attended a class sponsored by the FBI.
"And what we're doing is teaching state and local bomb technicians different techniques they can use if they ever encounter a bomb placed inside a vehicle," said Adriaan Valk, FBI special agent.
Every year, the FBI teaches what they've learned about car bombs to local police. The information comes from U.S. intelligence gathered in places such as Iraq and Afghanistan.
"Is it something that's going to come to the United States in years to come? Some say yes. Some say no. But, the program is designed to train state and local bomb technicians in case that threat appears in the United States," said David Bebout of Metro police department's bomb squad.
"We've taught them how to create the tools, how to place these tools in certain areas of the vehicle to get the maximum affect for disrupting the device. Not to set off or detonate but to disrupt the device so it can be rendered safe," Valk said.
The FBI would not show specific ways they try to disrupt a bomb detonation for security reasons. But afterward, the vehicle is intentionally blown up because police said they can learn a lot then as well.
Flying shrapnel such as metal and wood can kill, but just the blast itself can also be deadly. Overall, it's good information and one more way police can help make cities and neighborhoods safe.
The FBI said if anyone sees anything suspicious such as a package or a vehicle they should not hesitate to call local police.
