Furthermore, Östermalm has always been a place full of somewhat disreputable people, even though it ended up a place where relatively rich people lived. Notice that the story you're talking about involves prostitutes and all sorts of deranged stuff.
These people may have been associates of the upper class, but there is a reason we Swedes have always despised the upper class.
My point wasn't about the specific case (obviously multiple horrific murders are not a common occurrence), I meant the general milieu of drug addiction, law-breaking, prostitution; the disgustingly dirty slum conditions that people lived in - all of which was accompanied by police corruption and brutality.
Naturally none of this is popular to bring up in front of Swedes nowadays.
As I see that the downvote of my Swedish-negative comments speaks volumes about how much you guys value freedom of expression.
[Here](https://upload.wikimedia.org/wikipedia/commons/a/a0/Sweden-c... a graph from Wikipedia showing some violent crimes increasing, but the change is more than just the numbers, and the numbers could now be underestimates because trust in police etc. has dropped.
The social trust that existed even with strangers and for which there was good reason is largely gone.
