Gun violence and these explosions have been going up quite a bit last few years at least. Anecdotal (Sweden here) people in my closest circle feel a lot less safe, and less comfortable in public spaces, compared to a few years ago. Not to a huge extent, but noticeable.

Wait, is that question serious or you are really prentending you don't know what "changed" in Sweden, or in another European countries, over the past 10 or 20 years :-) ?!
