But, those references would also have to have their backgrounds vetted. Think of how many people would be unable to get that or would be too nervous to even try getting a gun?
But, for the "normal, everyday American" argument, it should be no problem to get those references and legally obtain the gun.
I don't see how that filters out everyone except for "normal, everyday Americans". Or rather, future radicals/criminals and future angry people can fall well within any reasonable definition of the term. So, how far do we keep upping the bar on what constitutes a "normal, everyday American", and if you really are one, you'll have no problem proving it by _____ ...?
So there'd be a strong argument that these are still half measures that don't stop criminals. I'm not against the references idea; it seems like a good way to filter out casual interest for a serious responsibility. It does not, however, filter out bad intent.
What would be a full measure, then? IMO, it's either:
1 - Precrime: find these 'potential bad apples' and strip them of their rights before they hurt anyone, or
2 - Decide that these are dangerous products, and restrict/remove them as necessary.
The only firearms that can be owned legally are shotguns, black powder weapons, manually-loaded cartridge pistols and manually-loaded center-fire rifles, all termed "Section 1" firearms.
I like what Enhance posted above. The English template seems to acknowledge #2 fully.
