In a word: MUSLIMS. These Arab and North African parasites not only live off the State, they are responsible for an alarming surge in rapes, murders, and explosions. All rapes reported in Oslo last year were by Arab and African Muslims.
No official is suggesting the need for criminal background checks for immigrants. A politician, Fabien Stang said when told about the massive number of rapes in Oslo, “Goddamn Hell, I don’t know what to do any more.” (Duh, I have an idea: Ban all Muslim immigration)
