Well where I live there aren’t nearly as many guns so the person breaking in would be less likely to have a deadly weapon and it would be a bit less risky to just call the police and hide, or comply with the (assumed) robber, or I’d feel like I’d have a better chance with using a blunt weapon like a bat to protect myself and drive them off, which would be less likely to kill someone. But where I live there are also a lot less robberies in general.
Doesn’t guarantee nobody would have died if the same thing happened in a place with less gun violence, but it might have reduced the chances. Even if people get into the same kinds of confrontations, if there aren’t guns involved the chances of everyone surviving a violent encounter goes up by a significant percentage. Less guns in a country over-all means less chances for a conflict to have a gun involved.
