Prepare to lead others in an offensive rally. Run/Hide/Fight is a good plan. However, so many schools choose to huddle kids in the corner of a classroom hoping the shooter won't enter their room. Once the glass is broken out, and the shooter gets in, he has sitting targets that have put distance between them and the shooter that can't be crossed without serious risk. I think most adults would be overwhelmed by 30 college students coming at him. I am a proponent of running, hiding, fighting, but if I were in a classroom I would instruct the others on their roles. Here would be my assignments: 3 or more to throw chairs at the attacker (first volley) The rest to be prepared to throw other objects such as books, jackets, backpacks (distracting, obscures targets) 2 to set large objects out of kilter as distractions (tables on ends, jackets hanging from lights, etc.) before the shooter enters 3-4 four brave ones (including me) to physically tackle the attacker as soon as the chairs are thrown, the goal to be getting him down on the ground quickly 2 to run past and get help/ first aid 1 to be ready with binding to tie up the attacker (jacket sleeves, belts, etc.) 2 to call 911 and report classroom location I may be hit by bullets, but I'd be falling toward the attacker and would make an opaque block to his field of vision. I will NOT hide in a corner or play dead waiting for the bullets to find me. In the scenario above, no knives, or EDC tools were necessary. Overwhelming force may be the only choice. I feel that if all schools/ churches openly practiced this, shooters would no think of these establishments as such free and easy targets any longer.
