The United States has over 4 times more murders per capita than France, for instance.
One thing a lot of people seem to forget is that the US has significantly more income inequality and significantly less social safety nets than France. Poverty drives crime.
What the US needs most is nationalized healthcare, deregulation of marijuana to cut down on mass incarceration (which breaks up families and drives poverty), actually taxing the rich, and better regulations and workers rights to prevent corporations from exploiting everyone



Most gun owners have more than one. If you’re a hunter, you might want to shoot different rounds for different game or seasons.
My state bans the use of rifles for deer hunting in most circumstances. In that example, you’d want 12ga for deer hunting, 20ga for duck, and 5.56 would be used for coyotes, boar, or groundhogs. And if you go boar hunting you’ll want a sidearm (9mm or .45) because they’ll gore you if they get the chance.
So that totals 4 guns for a single person with decent reasoning. Plus, if you had kids and took them hunting, you’d want at least 1 more of each type.
And for people who live in non-rural areas, you might decide to concealed carry a 9mm for protection. But handguns aren’t as ideal for home defense, so you might want a shotgun or 9mm carbine for that task, so that’d be 2 guns for 1 person.
