Thousands attended the 18th annual safety expo at Westroads Mall Saturday.
WOWT Six News got an exclusive inside view of how law enforcement handles serious car crashes.
"It's good for the public to know the resources that we have, when it comes to potentially saving someone's life," said Officer Jennifer Nelson, with the Omaha Police Department.
The expo allowed local law enforcement to interact with families and show them how vehicles and equipment are used in various emergencies.
There was also a live demonstration where WOWT Six News reporter, Lena Tillett, was a victim who needed to be extricated from a vehicle and flown by LifeNet to a trauma center.
When a victim is extricated from a vehicle, immediately a fire engine, medic, and truck are called to the scene. Several firefighters work together using a tool called "the jaws of life" to cut through a vehicle-- removing the doors and possibly the roof.
The victim is quickly put on a stretcher and placed on a LifeNet helicopter. The two paramedics or nurses on the helicopter are trained to handle a wide range of critical injuries.
"You know it's good for the kids to see this in action so that it helps them not to be afraid if anything happens in the future," said Jamie Billerback, a mother who attended the expo.
