Completely.
Personally, I wouldnt trust another parent to teach my child gun safety. That is my responsibility. A BB Gun may not be lethal, but it's a gun none the less.
Teenagers, especially 13 year old boys, will push thier boundaries. This 13 boy was no exception. This young man already made a very poor decision with gun. He not only took it without permission, he shot it and caused over a $1000 in damage. What if he had shot it at one o jasons kids and hit them in the eye? What I he had hit another child who was not Jasons? Jason and his wife could be held liable for medical damages for another child. Personally, fromhere on out this BBGun should be locked up and only brought out when supervised, because obviously poor decions are being made by jasons kids friends.
