Did you also experience bomb attacks? Apparently, there were over 100 bomb attacks in Sweden this year. Our Eastern European country has twice the size of Sweden's population, and we had zero bombs going off, possibly since the 90s, as I don't remember any. Gun violence is really low here too, we barely remember any that made the news.
I'm sure that Sweden is a nice country to live in, I've visited it, seems great, but ignoring the crime wave is short-sighted, and I don't understand what “high standard” you're talking about.
