Four Kokomo Police Department officers get ready to storm the building. Equipped with masks and air soft guns, they rush into Ball State University's Johnson Complex.
As the officers run in with an instructor following them in a neon vest, they find a disheveled room with chairs and mattresses festooned along the floor.
They move through the room, patrolling for any shooters, and they pass through a door. As they enter, the lead officer trips over a string that is attached to a chair.
"It's a booby-trap," one of the Kokomo officers said.
"All right, the first officer is dead," the training guide said.
The first officer - the one who tripped the trap - drops to the ground. The others proceed with their emergency response exercises. In this case, the emergency is a shooter.
Gene Burton, Ball State's director of public safety, said the training sessions combined classroom work and a realistic simulation to teach about 70 officers how to combat an active shooter.
"I think they are vitally important," Burton said.
Plans on paper are important to have, he said, but plans lose value if officers don't have hands-on training in those situations. Also, campus incidents such as the deadly shooting at Virginia Tech in April 2007, emphasize the importance of these exercises. Tech student Seung-Hui Cho killed 32 before taking his own life.
Ball State held a similar training session five or six years ago in the Burris Laboratory School. Training events occur throughout the year at various locations in Indiana.
"We try to do something to this effect yearly," Burton said.
The cost of the exercises would be minimal, he said, but most of the costs would be labor costs where departments would pay officers and instructors overtime for the training.
Russ Tussey, a Peru Police Department officer, said training sessions such as these offered the most realistic experience for an officer trying to learn what to do with an active shooter. Tussey said he went to Ball State's training instead of police training sessions elsewhere because of the realism its course would offer.
"As a law enforcement officer, our job is to move toward that target," he said. "That's the most difficult part. That's why we train like this."
Tussey said the training offered applicable knowledge because there was always a potential to have a shooting happen at the local high school or an office building in town.
Jeff Whitesell, a Yorktown police officer, said he's attending the training sessions because of the importance of knowing what to do if a shooting ever happened.
"I don't think you can put a value on this training," he said.
Whitesell said he went to Ball State's training because it was local, and if a shooting ever happened at a local school, he would probably get the call. If a shooting ever did happen, he said, a police department could never get enough help.
The practice sessions occurred Monday and Tuesday and will continue on Friday. Officers go through one, four-hour session to complete the training.
