Not only that, the violence is largely concentrated in a number of areas where the homicide rate is markedly higher. Both the number of these areas as well as their size are increasing, as does the intensity of the violence.
Possibly the biggest problem in Sweden is that it is still taboo to discuss the facts around this increased crime rate, even though those facts are well known and have been confirmed many times. As long as this taboo persists it will be impossible for Sweden to do anything about these problems as any action which goes counter the narrative of those who prefer to look away will be branded: racist, xenophobe, islamophobe, 'against our ethical foundation'[1], hostile to strangers ('främlingsfientligt').
Good examples of this can be seen in the recent spat at KTH (a technical university) where a student was about to be sacked because he'd made a document summarising the results of different studies on the subject of the relationship between rising crime and the number of immigrants from the Middle-East and Africa. The document itself did nothing more than summarise the results of these studies but this was deemed unacceptable because it was said to violate the institute's 'värdegrund'[1]. KTH directly violated the Swedish constitution which guarantees freedom of expression [2] but it was only when the subject was taken up in several alternative media that KTH backed down. Regular Swedish media did not publish anything on this subject until much later.
A similar case just surfaced where a school rector actually reported some students to the security police (SÄPO) and regular police for publishing a similar document, again just a summary of conclusions of official reports [3]. It is highly unlikely that the police will do anything, let alone the security police but the mere fact that publishing statistics can be ground for removal from an institution or reporting to the authorities shows how deep the taboo goes in certain areas.
[1] The Swedish concept of 'värdegrund' and 'allas lika värde', a form of non-religious dogma which trumps law and common sense in that violating it directly raises a black flag. It can be summed up as 'moral relativism'.
