Anyone know why americans are relatively unconcerned about dying to totally preventable stuff like disease?

You can't make concentrated firearms to smuggle into a country. They're bulky, expensive and made from metal. They're not heroin. Also, most of those illegal guns were legally purchased in another US state with looser laws, not smuggled in from another country.

Yep, they purchase them unlawfully because legislation isn't a quick fix.
- They purchase them from straw purchasers who get away with it because of lax laws in some states. Most states with stricter gun laws, the guns on the streets come from states with lax gun laws. If there were no states with lax laws there would be less of those guns on the streets.
  
  It's sadly not as simple as that when there's already a lot of guns in the country. Realistically that can't be changed in the current system. What would help in the immediate future is PSAs, training for professionals, risk assessments etc that can identify perpetrators. It's not massively expensive and can be implemented in the existing system.

Which other countries with stricter gun restrictions than the US regularly have school shootings?

Yes, I agree publicised school shootings are generally in the US. Did any of the other countries go from firearms being lawful to unlawful over the last few decades? The US has a huge amount already there, and that's a significant difference.
- Australia did it in 1996 and has only had one mass shooting since then in 2018
I don't feel countries can be compared like that. School shootings are often carried out by juveniles who can't lawfully get a gun. They're committing mass murder showing they're not law abiding. Realistically there's so many guns in America that even making guns illegal wouldn't prevent guns in the country.

Instead there's other things that could help, such as training professionals to identify perpetrators and warning signs they're going to attack. PSAs could be done so people can ID people around them.
- ^OP, here's the answer to your question
  
  (Intellectual laziness and uncritical acceptance of propaganda).
  
  School shootings are often carried out by juveniles who can’t lawfully get a gun.
  
  Cut this crap, this isn't reddit. Most kids them get the guns from a relative or friend who obtained it legally and adequate storage laws reduce both suicides and homicides in kids. BTW, guns kill more kids now than cancer or car accidents, but only in the US. Your take is the best example of americans being unconcerned about preventable deaths.
  
  Please let me reassure you, thats inaccurate. I do voluntary work in DA, work in the supportive sector and have personally funded related uni courses (DA being linked to crime perpetration, incels, firearm misuse etc). I've done considerable research into academic articles on lone actor grievance fuelled violence. I do far more than the average person does, I just have a different perspective... partly due to the academic research I've read.
  
  Please let me reassure you, thats inaccurate....
  
  What's inaccurate? I made like 5 statements.
  
  Guns kill more school-aged kids than motor vehicle accidents and cancer (i had to recreate the stats from the CDC wonder database myself excluding anybody over 18 because schmucks kept on complaining about the NEJM article including 19-year-olds, which apparently invalidated the data, except that it didn't)
  
  Gun suicides are mostly committed using firearms from friends and relatives.
  
  If you look at UK's homicide stats and the US's (BJS) homicide stats you can tell that actually the homicide rate difference is driven by firearms.
  
  It's a fact that it is much harder to kill someone including oneself without a gun.
  
  States that have gun storage laws have lower firearm mortality in kids.
  
  Blablabla on your trust me because I did some research. I'm in academia and published half a dozen (non-gun) epidemiology papers to date as a side hustle so I do know how to use the CDC databases. I've been forced to dive into the gun violence data because I'm really fed up with all the disinformation.
  
  What I have seen no supportive evidence for to date is "that training professionals to identify perpetrators" ("hardening schools?") has any effect on school shootings.

  Now let's see your papers.
  
  I'm referring to the personal remarks you made about me, they were inaccurate. Do you retract them?
  
  To be clear, I don’t know you, and there’s nothing personal intended in my remark. I do know this learned helplessness, however. It’s just weird that the same Americans who shockingly often expect me to cure death (literally) suddenly behave like NPC’s bouncing off a wall when it comes to lowering gun deaths.
  
  Thank you.
- Sure, the shootings won't stop the day legislation changes. But it prevents more guns from entering the US, making it more difficult to get one, even illegally.
  
  I get that some people in the states need guns. Some communities have a real danger from bears etc. But those people can get a license to own a gun, the way it works in most countries.
  
  Yes hopefully it would. It's a slow drawn out process though, and america isn't an island. It's not a fix
  
  Its not a fix, but a start in the right direction.
  
  Yep, given the reality of how many firearms there are already, and the resources it would take to remove them... I think we should focus on other things.
  
  Who says the government needs to remove them? There could be a grace period of a year or maybe several years, during which people already owning a gun can apply for a license and receive the necessary training. Those who don't want to get the license can come in to prove they made the firearm unusable. Anyone else owing a gun can be made liable after that grace period. This would minimize necessary resources.
  
  Also, a proper government should be able to focus on several things. And I do think daily school shootings is something worth focusing on.
  
  I agree that this is worth focusing on. Your suggestions would help. Sadly that doesn't remove the firearms already in the US. Meaning that criminals can obtain them.
  
  Perfection is the enemy of progress. You need to think more long-term.

It works in every other country.

Is there another country that illegalised guns when there were already a massive amount in the country? I'm unaware of one but happy to be enlightened if there is.
- Buyback programs tend to work, because they're "no questions asked" and illegal guns still get bought and taken off the street. Australia did one that was very effective, though they're cheating since it's an island.
  
  But one thing you have to remember is the US is the largest source of illegal guns in the world, because it makes them legally and they get smuggled. 40% of guns used in crimes come from just four manufacturers.
  
  If the US stopped making so many fucking guns it would actually make the whole world safer. Especially Mexico! Trafficked guns are the main source of the cartel's armory.
  
  It's a fair point on ceasing manufacturing, I agree that would help with preventing incidents for future generations.

Probably something like 99.9% of guns or more are legal guns when they're manufactured. If there were fewer legal guns produced and out there, there'd be fewer illegal guns for criminals, would-be or otherwise, to get their hands on.

Yes, it's a slow fix though
