It is an important analogy.
I think that is why we are about to see an end to major school shootings.
A pattern of attacking the shooter immediately is emerging similar to what happen in Flight 93.
Aspirant thrill seeking killers will shift their mode to some other form of crime such as tylenol tampering etc. It will become to risky to pull out the gun at school.
So which is it, aspirant or Tylenol?
