They don't really need the DNA, they just want it XD There is a sort of ID card out just now, but it's like a tester and it's not compulsary. The UK has the largest DNA database in the world. It's getting pretty ridiculous u_u As far as I'm aware, the UK isn't a Schengen state either.

God, the more I think about it, the more I hate this place D: You damn liberated mainlanders!
