Somebody is going to go to court. Just a question of which side gets there first and then how much teachers or students actually get out of the award.
Sounds to me like there are two options being offered: 1) how to put yourself between the active shooter and your students so you can delay their massacre for x seconds or 2) how to figure out how many fat kids you can get in front of you before you too are killed.
If they are not going to allow teachers to be armed (a tactic I have great reservations about*) then they should at least be drilling teachers and students on how to bail out of the building/grounds via non-traditional routes and methods.**
stay safe.
* - as we all know, not everyone who can hit a target is willing to pull the trigger on a homan being, regardless of the provocation. How does one test for that willingness?
** - too many schools have been retrofitted for "energy conservation' which includes bricking up those large banks of windows and eliminating even narrow windows that open to fresh air. For those not retrofitted, how many have had glass panes replaced with break-resistant plexiglass/polycarbonate? Back in the day youcould either just open the window wide and get out or use a chair/desk to break the window. Nowdays too many schools funnel to a limited number of exit doors, often with limited or no alternative exits. Bad enough for fire drills, but literally murder in active shooter situations.
