I think that proper age-appropriate firearms safety should be taught to every child. If we live in a society that sees firearm ownership as a right, then everyone should know how to exercise it properly. I was taught both this and basic marksmanship in high school, and I still enjoy target practice at the range from time to time. It can be quite enjoyable and quite challenging as a sport.
When I was much younger than that, I did not know how to handle them properly, which could have resulted in tragedy. Case in point, both my younger sister and I found a pistol when visiting my grandfather in about the third grade or so. Our parents were not in the room at the time. Had we picked it up like any other toy, we could've ended up on the 6pm news simply because we don't know any better. In hindsight, we should have been taught what to do in that situation as early as possible.
