What isn't necessarily considered here is that (In Switzerland, at least) many people don't actually have a loaded gun - Some places will offer to keep your gun, ammunition or both in another location, which saves you having to secure them &c. On top of that, everybody is necessarily trained to use said guns and by extension trained to be responsible with them. That said, I agree completely that the problem is not necessarily the presence of guns.
