Inevitably, the Hamzas are the ones who make the headlines, but it’s a much smaller case that sticks in my mind. In November 2003, Aso Mohammed Ibrahim, an illegal immigrant, knocked down 12-year-old Amy Houston and left her to “die like a dog”, while still conscious, under the wheels of his car. Ibrahim was driving while disqualified, but after serving a mere four months in jail, he committed a string of futher offences. The deportation process was so complex and drawn out that he also managed to father two children. Immigration judges ruled that sending the man who killed Amy back to Iraq would – you guessed – “breach his right to a private and family life”.
