I was watching one of those scandi noir series the other day and it came to me that genre basically exists because on some level they know they are building up both criminal and emotional issues from to their liberal attitudes to crime which they are going to have to face some time in the future. If you watch Paul Greengrass's film about Breivik it's actually quite horrifying how people aren't allowed to express their emotions over the attack and you can see how even the victims have to repress themselves to be considered decent people (the director himself though that was a great trait). This is clearly going to blow up (and possibly Breivik was already part of that) which is why their dramas are full of sadistic vigilantes and covered up past abuse upsetting people's seemingly comfortable lives.
