The 2nd amendment also does not mention anything about deranged or psychologically damaged people>>>>>>>>>>>>>
Correct. And the right to defend one’s life does not depend on anyone proving they are NOT crazy.People are assumed to be sane. Teachers who are hired by a schoolboards are assumed to be sane.
As a matter of fact, despite yout faulty logic, you also are assumed to be sane.
And there should be no “comprehensive” tests or checks on any teacher who wants to have the benefit of being armed.There should be training however, and periodic qualification of training standards.
Even conservatives these days find it challenging not to be liberals who think the world has to proove itself sane before anyone in it can even get a bus ticket.
