Felons tend to ignore most laws. If they're going to break into my house and attempt to steal a gun, then they aren't going to get one. But should they break into yours, then they could walk out of there with a gun. The simple fact that one was available increases the chance that it does fall into the wrong hands. How many stories do you hear of children shooting their parents by accident? No gun no shooting accident.

As for fitness and eligibility. There are some measures in which you could feasibly employ to prevent the wrong people being able to lawfully acquire those weapons. Such as much more stringent vetting. Example not just anyone can go and work in the nuclear industry, they vet you thoroughly. Yes it's a long and expensive process, but perhaps more stringent vetting would help towards limiting gun ownership to a group of people who understand the responsibility they have as gun owners and not people who refer to guns as "gats" and hold their pistols sideways. They don't have the maturity required to own a gun as I'm sure you'd agree.

I personally believe weapons education would be far far more effective as a form of gun control than the ideas that are synonymous with the phrase gun control. I'm not calling for a ban on guns, I'm calling for a way in which to prevent the wrong people getting the wrong weapons.

The problem is then about trying to mitigate those same wrong people from unlawfully acquiring those weapons and if a weapon is in a home and the home owners not there... Then they can feasibly force access and steal that weapon.

Just an idea but perhaps secure community locations for storage, like a community armoury of some fashion? You want access to your gun for sport, go and check it out use it and check it back into a secure armoury, where it will be kept secure preventing the possibility of someone breaking into your home for a weapon that's not there. You could argue that that just provides one singular place for them to target... But I feel a community armoury would and should have much much higher level of security than the average persons home.

Are you implying that the US has a lower IQ than Japan?

You're right it's not really a diverse mix of cultures so let's look back at the UK again. Do shootings occur? Yes. But they're are much much rarer than in the US because guns are not easily accessible. If you can't get a gun you can't do any shooting.

I would like to clarify, I'm not anti gun, I actually think you should be allowed to own whatever you choose to own within a framework of reason. And I can't see it as reasonable that an untrained civilian needs access to high end weaponry. The only modicum of anti gun I have is that I am anti the wrong people having the wrong guns.

Children as an example should not have guns, they should also not have access to their parents guns. And I don't mean "Timmy you're not allowed to touch that" I mean physically incapable of opening the locked container that stores the weapon. Although you have listed unhinged adults with severe mental issues as problems with shootings there is also the undeniable issue that children are taking their parents guns to school with them and doing the shootings themselves. That can't be allowed to happen.

I'm pro responsible gun ownership and I unfortunately believe that there is a large majority of the US population who are unfit to own weapons, despite what rights they may believe they're entitled to.
