People who think it's a good idea to walk around with weapons should be arrested.

Yeah, but criminals do not care, law-abiding citizens do... so who ends up being the victim in such scenarios? Typically the law-abiding citizen.

Not in any civilised country. Criminals do have guns in my country but firearm use is incredibly rare and use is restricted to crim V cop and crim v crim because police response and enforcement are so harsh for gun crime it isnt worth it unless it quite literally becomes life or death.

So then non criminals, while not armed with guns, face no real gun violence because even getting access to guns requires critical thinking and intelligence at least sufficient to understand risk vs reward well enough to understand civilian pop isn't a reasonable use case for firearms. Any firearm related incident here is a multi week news item. Stuff thats everyday in the USA and doesnt even make local news.

So, our cops and our criminals are armed, and i can trust my kids wont get shot up in school, i wont get shot in a store robbery, or by a disgruntled coworker etc.

You dont quite understand how bad it is I think, USA americans who move here have an adjustment period and usually need mental health support coping with leaving a country where getting shot in a road rage incident, for example, is a real risk. I had a colleague driving break down after cutting someone off accidentally, the cut off swerved ahead of us aggressivly stopped traffic got out and started shouting. Eventually wore themsleves out, as they do, got vack in car and kept driving. Didnt stress me too bad but my coworker driving totally shut down. Why? A year earlier a coworker in the USA did something similar and the person with road rage got out and started shooting at their car.

That's not normal. Not even close.

It’s also extremely rare here, when looked at rationally. Those kinds of shootings are limited to specific areas of the country. The other 99% of the country faces nothing like that, ever.

> police response and enforcement are so harsh for gun crime it isnt worth it

That's the key right there. USA enforcement is far less than what it needs to be, especially in (dare I say it) Democrat-controlled local districts.

The number of soft-on-crime DAs elected has increased significantly in the last 30 years, and the fraction of violent crime cases that are left unsolved has also increased significantly.

It's gotten so bad that a lot of conspiracy theories are circulating, like "Davos people want to destabilize the US, so George Soros is donating millions through his Open Foundation to soft-on-crime DA local election campaigns."
