The 2nd amendment might be a bit more hard for us Europeans to grasp. For some Americans it tends to be a very important thing, the idea of being free and able to defend yourself from danger. Here in Finland there are lots of guns, but most of them actually belong to hunters and then perhaps to collectors and some minor part of it are just gun-enthusiasts. You won't get a handgun for self-defence here and in most places it's now not so easy to get one easily either because you have to have a clear reason why you would want to have one. The police will decide if that reason is good enough for them, if you get a permit then the police will interview you at least once.
If you get a gun, they must be stored in a weapons cabinet. I think most common weapons here are shotguns and rifles. After that would come small calibre rifles, pistols and small calibre pistols. Deaths related to firearms seem to be relatively low and cops almost never have to shoot let alone kill anyone here, tasers are used a lot if needed. There have been only a handful times when there have been big shootings and sadly we did have two school shootings too about 15 years ago or so, before that it was still reasonably easy to get handguns. Before those shootings I was talking with my father about guns and possibly even considering to get one. I didn't consider after that and one reason was that even just the diagnosis for depression might disqualify you. I don't want the stigma of that. I would never even harm a fly, but how could the government be sure of that. At times I feel conflicted when I think about guns and violence.
Interesting video about gun control and the Constitution. Quite informative, something to ponder about.
