Tips On How To React To Active Shooter Situation

A man was shot dead by police on the Ohio State University campus after investigators said he plowed his car into students then began slashing them with a knife. 

Ten people were hospitalized, and the ripple effect of the attack is being felt by students in Oklahoma. 

Those who go to the University of Oklahoma in Norman say the college has offered them no training, and they’re scared.

"It's kind of scary when you hear about it on college campuses. It seems like it's more prevalent and I wouldn't really know what to do in a situation like that," said OU sophomore Jason Sookteo.

OU freshman Carolyn Dougherty agreed.

"I would not know what to do in that situation. Um, probably just, maybe try to run. But I don't know. You don't really know what to do," Dougherty said.

Ohio State sent students a tweet, urging them to “Run Hide Fight” -- recommendations from the Department of Homeland Security and endorsed by experts.

Run if you can find an escape route. Leave belongings behind and call 911 when you’re safe.

If you can’t run, find a place to hide. Lock doors and hide behind large objects.

"There are things you can do when you hide such as turning off the cellphone or turning the lights off in a room to not draw attention to yourself. But there are times that you cannot hide. Which brings us to the third part. Fight. You have to fight," said Jeff, the owner of Oklahoma Combatives Krav Maga school. 

Krav Maga is a contact combat system developed for the Israeli Defense Forces.

If you have to fight, students of Krav Maga are taught to be as aggressive as possible. 

"You have to go from zero to 1000 percent to save your life,” Jeff said. “You cannot just defend. In other words, you take the fight to the attacker.  You attack the attacker."

At Oklahoma Combatives, students are taught to use improvised weapons, like pens and fire extinguishers. They’re also taught to prepare for physiological changes to their own bodies during a fight, like tunnel vision and rapid breathing and heart rate. 

“Until you start training, go through scenario training so you know what your body's going through, until you do that you have no idea how difficult it is to execute each part of the combat plan.  Run, hide, fight."

OU students News 9 spoke with said they would like the college to offer classes on what to do if there is an attack on campus. 

"Absolutely,” said OU freshman Morgan Rahilly. “Because I want to be able to know, have some tips on how to protect myself."
