I agree, lack of common sense will cause laws to protect the children from their parents as well as opportunists.
As you see BB guns can be dangerous too it to a kid anyway they hurt. Got hit in the leg by a prankster using me for target practice. At the same time can’t remember if it was bird shot or BB guns but we were shooting for target practice bothers and neighbors and I decided it was getting boring so I decided we needed a live target. Not putting anyone at jeporday and knowing I was fast I decided to be the target. I ran back and forth not getting hit until a parent saw us and stopped it. Told us they could kill. I don’t think we even realized death is permanent. After all in cartoons they come back to life. Later on a child was killed by her bother using a bird shot hitting her in the chest his five year old sister. The chest wall thinner and passed through hitting her in the heart. Even BB guns need to be under lock and key and supervised conditions. Also saves money on broken windows and anything else they might hit.
