How to stay alive in active shooter situation

Would you know what to do if you came face to face with an active shooter? If you only had a few minutes to decide, would you run, hide or fight?

As mass shootings are becoming increasingly more deadly and common, some people say preparation remains critical to survival.

Hanan Yadin is a former Israel Defense Forces soldier. He helps prepare Navy Seals and SWAT teams throughout the U.S. for hostile situations such as active shooter scenarios.

Yadin says if you can escape, you should do that first. But if not, hiding is the next best option. But if you do come face to face with someone threatening you a weapon, Yadin says you should know what to do, including using your body as a defense mechanism.
