The entire culture has been dealing with the dark for almost a thousand years.

There's also the thing of highly regulated alcohol sales, which limits some possibilities of excessive behavior.

Also, I don't know where you are getting your firearm stats. Gun ownership is far less than half in Sweden, is much more regulated, much MUCH more culturally frowned upon. Contrast that with getting guns like candy in Walmart, or like me - shooting automatic weapons in the back woods before I was ten. I was constantly quizzed as to why Americans are so obsessed with guns. Sweden is much more like Switzerland than the U.S. in firearm attitudes and practices.
