My parents met at an ammo factory in 1966. Firearms have been a part of my life since before I could walk or talk. I don't have any friends that aren't shooters- notice I didn't use the generic term "gun owners". When did gun safes become common? Because I can tell you, I lived half my life among serious shooters before I met someone that owned one. At best there was a wood cabinet with a glass front and a $2 lock. Guns were stored in racks, in closets, under beds, in dresser drawers or if you had a hardcore gun crank, in the "gun room"- ie a spare bedroom/den. My best buddy growing up, his dad was a serious gun crank- guy had probably 250 guns, back in the 80's...they were mostly military rifles from the World Wars. There were at least three registered machine guns in there as I recall....They sat in the "parlor" on wooden revolving racks- row after row of them.
As a kid growing up I had a rifle rack in my room- I made it as a 4H woodworking project- got a blue ribbon for it too.....It held 4 firearms and the drawer at the bottom was full of ammo. I frequently carried a .22 rifle in my car on the way to school- buddies and I would go hunting on our way home. Hunters Ed was taught in the math class room of the middle school- I have pictures of 12 year old kids shooting .22's (shorts, into a pellet trap) in the Math Classroom- in the yearbook! This was not an uncommon thing by any means in this country and there were no serious problems with it.
I now have over 2,500 hours of professional instruction in firearms use and marksmanship, from some of the finest shooters and instructors this nation has ever produced- guys from CAG, the Seals, Marsoc, 8541's, Ground Branch, various SWAT Teams and Federal LE Agencies.....There are 4 Rules to Firearms Safety, they must be adhered to- 1. Know the condition of your weapon at all times (Notice I didn't say "all guns are always loaded") 2. Don't point weapons at things you aren't willing to destroy 3. Don't put your finger on the trigger until you've made the decision to fire 4. Know your target and background. Anything other than that is BS. It's not "firearms safety" it's PEOPLE MANAGEMENT. Maybe if people don't want irresponsible kids having access to guns- they should RAISE RESPONSIBLE KIDS? That might have benefits even beyond firearms safety- raising kids that were decent, responsible, functional, moral, human beings....The "safe storage" thing is essentially admitting failure, it's a cop out in my opinion- "I can't control my kids or my home etc...so everything needs to be locked up". That's BS.
As far as hunting "accidents"- see rule 4.
