Terrorists, criminals etc human rights, civil liberties of individuals or the few are not to the detriment of the many. Law breakers, rapists, groups that proclaim against our culture/way of life, can be imprisoned/deported at the end of their sentence despite their private life or risk of harm upon return. We have the right to go about our lives without other countries criminal etc roaming our streets, claiming benefits, legal aid etc to the detriment of the many.
Why does this idea matter?
So that the rights, needs, resources and requirements of this country and its law abiding citizens are not put at risk or abused by the few or individuals who pose a treat to the country or its inhabitants. Convicted paedophiles, rapists, terror suspects, benefit fraudsters and general criminals are treating us a soft touch and we are becoming a laughing stock with our 'Come on in and wipe you feet on us policies'.
