The capital of Sweden is probably also the European capital of rape. Since Swedish police, politicians and media do their best to cover the Muhammad-factor, we have to look at neighbouring Scandinavian countries for a reasonable explanation:
Rape jihad in Denmark: More than half of all convicted rapists have immigrant backgrounds. Iraqis, Iranians, Turks and Somalis dramatically overrepresented...
Oslo, Norway: 69 percent increase in rapes (76 rapes in 91 days). Share of non-Westerners among 'attack-rapists': 100 percent.
