I grew up around plenty of guns at my friends - they were moose hunting rifles mostly. And they were under lock and key unless actively used for hunting, with guns locked in one location, ammunition locked in another (at least one of them in safe).
The police where I live now (Ireland) don't carry guns except for a few special units.
The fact that wearing guns is something that is every day business and that you can even discuss about is so alien to me that it is fascinating to see. I am glad I dont live in a society with those values though.
More guns means more people killed by guns. That said, I don't know the solution once you already have a proliferation of guns in your society. Personally I don't believe that maximizing the saturation of guns is a long-term solution but I recognize that it is a difficult situation.
