I hate banging on about Romany Gypsies but i have to ask?

Do you know anyone who works at the airports, do you know anyone who works in the immigration control aisles or whatever they're called? If so how come they allow Romany Gypsies through? Before anybody retorts " how are you meant to know they're Romany Gypsies?" the plastic carrier bags wih all their clothes sort of gives it away. I don't understand it, no trade papers no skills they travel over in squads of 50, 3 men to 10 heavily pregnant women. Its obvious they aren't migrating to work. Can immigration control just not hold them for something and put them on the next plane out? Oh wait a plane going back to Romania thats a good one!
