Your parallel fails because there isn't any situation where driving a car in a mall (other than putting it into those spots for sale) really makes any sense. But lots of people all the time go in with concealed weapons without incident.
It works better than you realize (and BTW, you implied that concealed carry makes sense, but I certainly don't accept that idea).
A "good guy" in a car to protect from "bad guys" using cars violently makes way more sense than carrying a gun to defend against armed attackers. With a car, you get protection without doing anything yourself: you don't need to take the other guy out; the safety systems of your car protect you even if you're sitting in it motionless.
Also your point is moot was most malls disallow guns since they are privately owned.
But there are gun nuts who argue that this should change. They defend their position with arguments about how the mall - or church, or school, or wherever - needs "good guys with guns."
Shockingly it doesn't stop people from going there to shoot people who had their guns banned.
But it does mean that the second someone is spotted with a gun, we know something is wrong and respond before anyone is killed. If guns are allowed, you have no way of knowing that a person is there with violent intent until they start shooting.
Your argument would work in a place with almost no guns (like where you live). But you can't really compare it to a place like the USA that has more guns than people. Something the anti-gun crowd forgets is that reducing just a few guns won't stop the problem. You would either have to get rid of most guns already on the market and in private possession, or you have to have some degree of actual security.
It's not about reducing only a few guns. Any position I advocate is part of an overall goal:
- no semi-auto rifles
- no (or at least very limited) handguns
- for the guns that remain (mainly shotguns and non-semi-auto rifles), no allowances for defensive gun use: they have to be stored securely and unloaded, with the ammo stored securely separately. No "castle doctrine" - "self-defense" shootings would invite serious scrutiny and have to pass a high bar for the shooter not to be charged.
And yes: this would mean getting rid of a lot of guns already out there.
That said, some things like Universal background checks have widespread support, and I think those could help a lot. But the main tactic shouldn't be barring honest citizens who are of sound mind and have never committed a violent crime.
Why not?
The only argument I might take is that we should centralize gun ownership into independent militias separate from state and federal government. But I don't suppose you think that's a good idea?
Heck no. Private armies are an awful idea.
It's either that or private ownership. Those are the two only ways to interpret the 2nd amendment.
What I'm proposing would almost certainly need a constitutional amendment to implement it in the US.
EDIT: I know you're not in America I just am assuming pretty much all of this topic is about the gun situation in America since it is 99% of the time gun debates happen.
I'm talking about what I think the gun laws should be like in any Western democracy. How they could be implemented varies from country to country.
