Okay, then yes. I think we should. But it would never happen here. Not ever.
However, there are people who make the argument that the difference between this-firearm-that-is-banned and that-firearm-that-is-not is the banned one is black and the not-banned one has a wooden stock. Or this-specific-gun was banned so the manufacturer changed the grip and lengthened the magazine; so now the “new” one is not banned.
Also, I remember that after the night club shooting, Obama said he could GPS his phone but not a gun if he had one, that that should actually be a thing that is required, and we ought to invest in such a technology. I thought that was an interesting concept, if somewhat impractical.
Realistically, I just really think the culture will not do anything whatsoever until it hurts too much not to act.
