Yeah they were so big on immigration that now a substantial part of the population doesnt speak swedish because they dont have enough money/teachers to teach them proper swedish. A lot of people speak miljonsvenska(kind of a mixed language between swedish, english, turkish, arabic, etc) or just speak their own language. This creates dense pockets of crimes. In stockholm for example you can live a few metro stops from rinkeby, a place where theres a lot of crime, but you dont notice it because it doesnt leak out. Of course everyone is starting to notice how bad it is because sometimes it spills out.
How can you make those mistakes???
