When I was growing up, in north Idaho, everyone had a gun (usually hunting rifles) in their home, and we were all thought as children to NEVER touch our parent’s guns.
We were told to assume that any gun we saw was loaded. Most people didn’t carry around a handgun for protection, because we really didn’t need it; but I imagine that in the larger cities in the US, there would have been more criminals, and people might have needed a weapon to protect themself.
In high school, where some of the students drove a vehicle to school, every pickup had a gun rack in the back window, and most of them had 1-2 rifles year around, but especially during fall hunting season.
The high school principal didn’t object, and if he said anything , it was to admire the hunting rifle.
The worst thing that ever happened was probably some of the older boys smoking on the school grounds. No one did drugs, or was prescribed drugs.
It has been since the doctors started prescribing all of the mind-altering drugs to our school kids (and adults) that this epidemic of irrational killing has started, and most , if not all of the shooters have been on some kind of psychotic drug, and often had been prescribed ADHD drugs when they were school-age children.
It is not the weapon that is the problem here, it is the mind of the shooters.
