I teach high school art and ceramics. I'm old ... not in great shape ...and smaller than average. And I have very minimal H2H vs firearms training. Not enough to depend on under the stress of a
real attack.
We keep our classroom doors locked when class is in session. The windows are covered. If there is a "lockdown" called, we double check the door, shut off the lights, and get the kids down on the ground, quiet, and out of the line of fire from the windows and door. And we wait.
That's our school's policy.
If an attacker does breach the door, I plan on being ready off to the side of the door with a big freakin' rolling pin. I figure I might get in one clean hit. Then keep hitting as long as I can. Maybe I can knock him down, or knock his weapon down, or just get shot and die ...who knows.
If the attacker goes down I always have a few big, physical kids in my class. 17-18 year-old football players and wrestlers. I can't put them in harms way. But if they
choose to dog pile and
incapacitate (beat the bloody tar out of?) an attacker. I can't stop them. And I've told them as much.
BTW practicing with my escrima group, I've found that a simple downward strike from an ambush position at the side of an entryway seems to be the strongest, most instinctive, and most reliable at knocking down an extended weapon and bashing the attacker in the head. Think along the lines of a Dog Brother's "caveman" strike or chopping wood. It might work.
And yes, I know I might "die trying". Beats dying cowering behind my desk, I guess.
