I think many of us held back posting on this because of the shakey holds we have on our own reactions at this point. I know I avoid talking about it much with friends because I'm afraid of just how it may all spill out.
Recently I read an article online by a consultant that "hardens" schools by teaching the opposite of what is currently in style. While he agrees with lockdown, he also teaches classrooms and teachers how to switch from defensive modes to offensive modes. Throw books, desks, pull down the flag and charge the shooter with it like a lance. Do anything, but don't be content with being a crouching sheep target. The sooner the shooter is stopped the fewer victims there will be. Nobody would volunteer their child to be the one to try tackling armed shooters, duh! But how would you feel at the mass funeral knowing that many of the lives could have been saved?
People with differering opinions point to how the flight that crashed in Pennsylvania during 9/11 saved no one on board. They say the "Let's Roll!" philosophy failed. They forget the thousands of people that the hijackers had in their crosshairs. I would like to think I'd eat a belly full of lead for a chance to go down fighting, especially if it means someone else can grab the bad guy from behind and gouge out his eyes, sink teeth into his throat, snap kick his knee, stick a knitting needle in his crotch...and maybe save one innocent life.
God bless that principal that gave everything down to the last and final measure. God take them all into His arms and rest their souls.
