It’s weird because Switzerland is one of the most armed countries in Europe, as in they have firearms but barely any shootings of any kind (so you don’t often hear news equivalent to a guy shooting students in a classroom or killing people at a shopping mall over there). Part of it has to do with the draft (most people who purchase firearms have a form of training, as they learnt how to properly handle them during military service).
Because guns don’t cause gun violence; poverty, unemployment, drug addiction, and mental health issues cause gun violence.
Switzerland’s society and government place value on treating the underlying causes of gun violence. The US’s government has been captured by corporations who derive profit from the incarceration of people who commit gun violence.
Can’t gun violence without guns. If we can’t fix one component we need to fix the other.
