If someone simply proposed that with any gun purchase a mandetory gun safe had to be either bought or provided by the retailer/resaler, then that would remove any doubt that someone (i.e. "governement") is out to take away your guns.
If you already own a gun safe, proof of ownership will suffice.
I wonder how many accidental gun deaths occur each year due to the fact that the owner of the gun failed to store it properly.
