Philby, I know what you are referring to, and I have to say, it won't work
There are parents who will not allow their children to trains in safe firearm handling or counter force in a school system,
And to be honest? it's the moral equivalent of training a child how to drive a car so they can avoid driving a car.
You must understand that the undeveloped mind does not have the kind of "wisdom" you or I have, and that makes it reckless, not dangerous, but recklessness leads to danger.
We all know that, most DUI's don't believe they would have killed anyone, but bio metrics says otherwise.
I think that's established,
I don't mean to disaude what you are trying to do here, I understand what you mean, but you are talking about a pretty sophisticated way of thinking.
Fight or flight, are the basic biological instincts, we cannot legislate something like courage or fortitude, these are intangible attributes of the human pysche,
Some of us have more than others, and I am not sure that putting those attirbutes to the test IF something like this happens at another school is a good idea.
I know where you are going with this, but please, listen to me, do the causal effect review, you'll see why it won't work
Regards
Pace
