IMO This should go nowhere.. and I have never owned a gun.
The product was legal.. it's like running people over in a car a suing Ford .
The defects was the mom and the kid.
The kid was probaly over medicated since birth and the mom gave him access to an arsenal.
No commercial in the world will make a sane person go off on a killing spree
I do wish laws would change to required training and licensing.. we require that for driving but any nut can buy a gun.
