It’s not your real world, lots of other countries have so little gun violence that a shooting makes the national news when it happens and thats maybe once or twice a year.

There are countries in the EU which have pretty lax gun laws and firefighters are fairly accessible they still have fairly low levels of gun crime. Just having access to weapons doesn’t mean that people will start killing each other for no reason, there are many other more important factors.

It must be nice getting to live in an area that doesn't have entire subcultures dedicated to guns and crime.
