That's crazy, imo. All one has to do is move away from the window line of fire.
It's pretty clear from this tragedy that school lockdown procedures need review.

You try moving 28 kindergarten kids away from a window!!!!!
I don't think it is crazy at all.
My door is closed and locked, the window is covered and someone like AL cannot see me in my classroom hurrying my kids to the safety of our closet, so he leaves our room alone and moves on.
If the window was NOT covered, he could see me and the kids and shoot out the window and bang....we are dead.
Just because the open window idea is ok with your prison school, doesn't mean it is ok everywhere else.
