Swedish Professor from Karolinska Institute gives a Danish journalist a severe reality check

sure, only one individual was responsible for this particular crime, but let's not ignore the over representation of those of migrant backgrounds in violent crime in sweden.

I found this on wikipedia (https://en.wikipedia.org/wiki/Immigration_and_crime):

Immigrants are overrepresented in Sweden's crime statistics. In a study by the Swedish National Council for Crime Prevention in 1997-2001, 25% of the almost 1,520,000 offences were found to be committed by people born abroad, while almost 20% were committed by Swedish-born people with a foreign background. In the study, immigrants were found to be four times more likely to be investigated for lethal violence and robbery than ethnic Swedes. In addition, immigrants were three times more likely to be investigated for violent assault, and five times more likely to be investigated for sex crimes. Overall, North Africa and Western Asia were strongly overrepresented in the crime statistics. The report is based on statistics for those "suspected" of offences, but Stina Holmberg of the Council for Crime Prevention said that there was "little difference" in the statistics for those suspected of crimes and those actually convicted. "Slightly under 60 percent of the almost 1,520,000 offences ... registered during the period covered by the study can be attributed to persons who were born in Sweden to two Swedish-born parents," it said.[36]

and this on gatestoneinstitute (http://www.gatestoneinstitute.org/5195/sweden-rape , don't know how reliable this one is, but the relevant snippet seems to only be a citation of someone else's study):

Since 2000, there has only been one research report on immigrant crime. It was done in 2006 by Ann-Christine Hjelm from Karlstads University.It emerged that in 2002, 85% of those sentenced to at least two years in prison for rape in Svea Hovrätt, a court of appeals, were foreign born or second-generation immigrants.A 1996 report by the Swedish National Council for Crime Prevention reached the conclusion that immigrants from North Africa (Algeria, Libya, Morocco and Tunisia) were 23 times as likely to commit rape as Swedish men. The figures for men from Iraq, Bulgaria and Romania were, respectively, 20, 18 and 18. Men from the rest of Africa were 16 times more prone to commit rape; and men from Iran, Peru, Ecuador and Bolivia, 10 times as prone as Swedish men.

Swedish natives do have valid reasons to be angry with the status quo
