Teachers Go Back to School in Las Vegas to Learn Active Shooter Training

These teachers are going back to school to learn how to take down an active shooter in the classroom. Former SWAT team cop Dave Acosta is instructing some 200 teachers in Las Vegas how to protect themselves and their students from attackers. He runs "Fight Back," a program that trains educators how to defend with their bare hands. As part of the training, the teachers practice disarming a person as well as ambushing an attacker if they enter a closed classroom.
