"You don't want to freeze. You want to be in a position where you've thought about this and you know what you are going to do," Los Angeles County Sheriff Jim McDonnell said.
The sheriff's department produced a startling and graphic video titled "Surviving an Active Shooter" to help people prepare for active shooter situations.
"This is something that you know shocks the conscience. And that you want to be able to have internalized that beforehand so you are ready for that so when it does happen automatically you know what your three options are and that you start to exercise those," McDonnell said.

Sgt. Harry Drucker with the sheriff's department produced the video and said the scenarios are based on or inspired by true events.
"When they do occur, there is blood. There is violence and we don't want to sugarcoat any of that," Drucker said.
The sheriff's department said you have three options during an active shooter situation: Run, hide or fight.
"Get out of there if you possibly can at all. If you have to hide in order to protect yourself then do that. And then, worst case scenario, you have to fight. You just can't sit there and be a victim," McDonnell said.
The nine minute video gives tips on what to think about before and during the attack.
"When you go into a mall, when you go into a store, a theater or anywhere, know where the exits are. Have a plan so if something were to happen on this side you know you're going out on that side. Always think two steps ahead," McDonnell said.
