NORTH LITTLE ROCK, Ark. (KTHV) - What would you do if you were in an active shooter situation? One gun store owner said there is a way to condition yourself to be better prepared to make that decision. And he's bringing that training to Central Arkansas.

Many of the victims of the Las Vegas massacre have said when they first heard the gunshots, they thought they were fireworks.

"When you see some of the video from the shooting in Las Vegas, there's a period where people are standing almost in denial like, 'Was that gunfire?” said Nathan House, owner of Arkansas Armory, a local gun store.

House is also a Constable with Lonoke County. He said the reaction in Las Vegas is a natural human reaction, but also one that can be retrained.

"At that point, they have to deliberate what they're going to do in that situation," he said. "Have they already taken the time to know what plan they would take in that situation? Do I know the exits? How do I get there?"

He is certified to teach Civilian Response to Active Shooter Events (C.R.A.S.E.), a program that teaches people to think about those things in every situation in daily life.

"It's understanding that human response and then making preparations in advance so that whenever you find yourself in that situation, you may know what you're going to do," House said.

House posted on his Arkansas Armory Facebook page that he's is a trainer for the course, and following the horror in Las Vegas, wanted to host a training.

Within 30 minutes, the 18-person class was full and the demand was still there, so House plans to open more classes to the public.

"For me, it was very important to get this information out there absolutely free," he said, "so that we can save lives, if God forbid, people around here ever experience a mass shooting."
