The terrorist attack in Sweden was not exactly "non-existent". What it has turned out to be, in fact was a right-wing neo-Nazi attack by some skinheads - who have all now been arrested - on an immigrant centre. In referring to this one incident which happened several months ago, SCROTUS hasn't really made his case against immigration, except indirectly that the presence of immigrant centres tends to provoke backlashes from insecure white male idiots. Sweden remains unmoved otherwise and some economists are crediting the immigrant intake with the excellent economic results achieved by the country in recent weeks.
