If it happens on Swedish soil, then it's just a matter of time before it expands to other areas. It might not be in your area yet, but the increase of those numbers has to be worrying. Maybe not now, but it shouldn't take more than 10 years.
Sweden hasn't actually collected crimedata on the non-native people living in Sweden since 2005. Don't you find that worrying? Since your take on immigration has been liberal, your country is literally going to shit.
