It's unfortunate, but it's understandable that "regular" people want to minimize risks by e.g. avoiding the unknown. What I mean is that you can't really blame the typical citizen who sees something unknown, reads the news and is concerned about his/her property.

Non-western immigrants in Sweden have a bad reputation, simply because integration has been handled poorly by the government (and their immigration policies have arguably been way too open), and that people come with all kinds of backgrounds, war torn countries etc.

It's a chicken and egg situation, I think the best thing Sweden can do at this point is to partly shut the doors on immigration and focus on integrating the population currently living in ghetto like suburbs.
