But as for the real issue... Again, when you say "right to access a lethal product is not maintainable when the proper functioning is strictly punishable" you are forgetting a whole body of strict-liability called "
Ultra-hazardous" which includes transportation, storage, and use of explosives, haz-mats, wild animals and others. Use/storage etc of these is strictly punishable and the right to access has continued so we coul similarly craft a strict liability system to encompass firearms/ammo. As you have already said, guns are intended to harm people, so I see no reason that the makers, wholesellers, retailers etc should be able to escape the burden of the consequences, while the Sandy Hook parents are forced to bear the burden... Unless we really, really, really want to make guns a sacred cow for some reason, (like fear, fun, freedom & founding fathers)... which we do.
