Isn't that because of immigration?
It depends Yes and no why it has become like that because Sweden gives a slap on the wrist.
Its no different to San Francisco with high rates of drugs, suicide, homelessness, rape.

Sweden crime problem even affects immigrant communities more than the natives. Most immigrant communities live in slums.
Nordic countries in reality might be the most developed on the planet but the society itself there is something not right there at all.
