State Police are helping Acadiana law enforcement deal with rapid response situations.
The training was Thursday on the UL campus.
Here's the setup for the exercise. What police call an active shooter is causing havoc in Denbo Hall. That's a person with the goal of causing as much carnage as possible in any type of crowded building.
It was only a drill, but the lessons learned will help area agencies coordinate plans if or when a crisis is underway.
Teams of officers storm the building to find the best way to subdue the suspect before more people are hurt. It also teaches them to deal with real life factors like innocent civilians still trapped in the building.
Police say the Virginia Tech crisis took only about 10 minutes from start to finish. They say that's why every minute counts during response.
