Absent something that dramatically shifts public opinion the political will doesn't exist. Doesn't mean that it won't at some point in the future or that as demographics shift public opinion changes. I was focusing more on the legal and practical nature of what sensible policy might look like not the prospects for immediate implementation, which are nonexistent currently.
Also gun ownership on a household basis has dramatically declined over the last couple decades while gun sales exploded. A small number of people bought an utter shitload of guns. The actual number of people this would effect is a lot smaller than most people would conceive.
Right now the tree of liberty is being watered with the blood of school children. We have a gun culture problem and it's become an unhealthy fetish....
For the time being, Enshrining of a particular kind of weapons ownership as a fundamental constitutional right is the root of the problem, and the problem will not really be successfully addressed until we change that. And that will take a while.
If we fix that issue, we could still have quite a few people legally owning quite a few guns without it causing severe social problems. As is the case in many other countries where gun ownership isn't considered a fundamental right.
It's the perceptual distortion of a particular kind of weapons ownership into some imagined essential manifestation of patriotic liberty that is at the heart of our society's fuckedupness on this issue.
I own serveral (more than 5) firearms and enjoy them as a hobby and don't want to stop most law-abiding people from being able to own them. The root of the problem is ultimately our nation's gun rights fetish culture. And the root of gun rights culture is the placement of gun ownership in the category of fundamental rights. At least now the parents will have the consolation of knowing that their children's sacrifices were completely in vain and that nothing will change. I would not want them to be suffering under the illusion of false hope or wasting their time and energy campaigning for sensible gun laws. Mass murder is accepted in the United States and no amount of dead kids will change that.
