Transcript for Surviving an Active Shooting Situation
O. So let's bring in ABC news consultant brad Garrity, a former special agent with the FBI. Brad, good morning. I've got to ask you how rare is it for a suspect in an active shooter situation like this to voluntarily surrender? It's quite unusual, Dan, as we experienced in Paris and other places where islamic extremists have taken over and have a hostage barricade situation, they're going to die at the scene one way or another. The small window you have with maybe this type of shooter is either remorse or he just finished what he started and it was time to end it and he chose not to die. After Colorado Springs and after, of course, what happened in Paris two weeks ago, a lot of people can't help but wonder what should we do if we find ourselves in an active shooter situation? Is it as simple as calling 911 and waiting for 9 police to show up. No, you have to take care of yourself. If you can run, run. If you can't do that as this person you just had on described, hide. Secrete yourself someplace, shut the lights off, your components off or on silent and wait. Make sure you continue to listen because you may have to change your location. The last thing is you have to fight which means anything that you have, a pen, a pock knife, anything you can can go at this person because you now, this is the last resort, he's going to shoot you so you go at him. If you can get other people to go with you, that is extremely important, in fact, that's one of the teaching tools today in schools is everyone at mass start throwing stuff at the shooter and go at him. Great advice. Hopefully none of us has to use it. Brad Garrity, we appreciate your guidance on a Saturday morning, thank you.
