Det er efterhånden almindeligt kendt, at legaliseringer ikke løser problemerne, hvis ikke indvandrernes forhold forbedres, men at de tværtimod næsten altid forværrer dem, eftersom de kun giver næring til udstødelse og udbredt kriminalitet, der ofte munder ud i terrorisme.
It is widely known these days not only that legalisations do not allow problems to be resolved without immigrants' circumstances being improved, but that they nearly always exacerbate them instead, merely encouraging marginalisation and widespread crime, which often result in terrorism.
