It's been close to a year since the mass shooting in Las Vegas.
Today, Lieutenant Josh Bisko of the Las Vegas Police Department spoke with local law enforcement at the Wisconsin Chiefs of Police Association conference in Green Bay. Lieutenant Bisko responded to the shooting.
He explained what police could face if they ever got the call to a mass shooting.
Lieutenant Bisko was on one of the teams responding to the hotel room the shooter was in.
NBC26 was not able to speak with Lieutenant Bisko because he did not have permission to speak with media, but we did speak with Chief Christopher Domagalski of the Sheboygan Police Department who attended the training.
He said Lieutenant Bisko was involved in the breaching of the door to get into the hotel room.
He added Lieutenant Bisko demonstrated some of the chaos and panic to give officers a better understanding of the situation during the training.
"You would never expect it. Those types of things to happen in our cities, anywhere. So the reality that the threat is out there, and that if you plan, you build relationships and work with other partners, you can hopefully prevent some of these incidents, and then better respond when unfortunately we have to," said Chief Domagalski.
He added Lieutenant Bisko compared responding to the Vegas shooting to others he has had on the job, saying this experience impacted him so much more.
Officers said this training will allow them to share with their own departments the best ways to respond if they are ever called to a mass shooting.
