"Whether or not Molenbeek, Rinkeby, and the Marseilles slum are no-go zones, then, depends on what aspect one chooses to emphasize — their accessibility to ordinary visitors at ordinary times or their inaccessibility to government officials in times of tension. There are also no-go gradations, some places where attacks are more frequent and violent, others less so. However one sums up this complex situation — maybe partial-no-go zones? — they represent a great danger."
