We're not going to stop them. They are an emergent phenomenon of American society. So many things would have to change that this country would be unrecognizable. Which might be awesome... but it's not going to happen anytime soon.
Britain, Australia, Canada, New Zealand, and Norway all had a culture of gun ownership, went through a mass shooting, put severe restrictions on gun ownership, and had dramatic drops in gun violence. All those other countries have similar mental illness rates and other things people blame mass shootings on.
Yeah man. I'm not saying that guns aren't the main issue. We have more guns than people here. It isn't gonna change though-- especially not right now. Gun purchasing seems to be accelerating if anything. Yes, if you or I could snap our fingers and have all guns disappear, that would do it. Actually getting from where we are now to where those other countries are does not seem like a very clear or likely path. I simply cannot imagine the US as we know it becoming that other place.
When Australia banned semi-auto firearms and handguns for general ownership, I was hearing about hiding guns from gun owners around me
If they did, they've kept it quiet, and probably left them buried
But really almost all the banned guns were sold to the government during the buy back, and due to the amnesty many previously illegal weapons were also turned in
It went really well as the worst people for owning guns also really wanted the cash for turning them in, and if they hide them, they're hiding them against an imagined future crash, and cannot really bring them out normally
The issue is that attempting gun restrictions will cause an extremely violent backlash. The reality is that the United States is going to face ever more violence before enough people suffer enough to change.
Those restrictions didn't do anything because they targeted the groups of guns and owners who aren't actually being used in crime or shooting people.
There are sane things you can do that actually help, like requiring safety courses and having regular background checks. Canada already does this and the Conservatives didn't touch this.
Then there are things which arguably do not increase safety but do increase burdens on gun owners and society, like forcing people to register bolt-action hunting rifles (used very rarely in crime), or secure an ATT (Authorization To Transport) every time you want to move a gun literally anywhere, including to hunt or shoot at the range. These are the things the Conservatives changed to make less overbearing because no one could prove they actually help and they were costing a great deal of money. Fun fact: restricted guns are still registered in Canada, and that includes nearly all legal handguns.
