You leave them there until they come clean and say where they came from. They know where they came from. Arriving having destroyed their paperwork is deceitful and dishonest. If we are to have more citizens, it would be better to have honest ones, rather than those who employ every criminal, deceitful trick in the book to get here. 

But in fact..we do not need even one more immigrant..This country is stretched to the limit, and employing austerity measures. One look at the Mediterranean should tell us that we need to be in control of our borders. The whole human demographic is changing at the moment, and the numbers of migrants will increase dramatically over the summer months, even more so in the coming years. Frau Merkel caused untold damage inviting over a million to Europe..and now there are tensions there. The new wave of migrants are not from Syria, they are from North Africa. We cannot save the world. For every one that we allow in, a thousand will follow. Like Evo, I am sick of the bleeding hearts who are afraid that the rest of the world won't like them....we need to toughen up now...and leave that poisonous club.

So it's OUT for me...bring it on.
