When I was 13 I took a firearms safety course. That was in 1956. Here’s what stuck from that course:
1. Always point the muzzle in a safe direction. All guns are loaded.
2. Never enter a building with a loaded weapon.
3. Never enter a automobile with a loaded gun.
4. Always store the weapon unloaded and separated (far away) from the ammunition. With today’s emphasis on locked storage, firearms should even be safer when not in use. If these rules had been followed, three youngsters would be well and alive today.
