I remember that the first time that I arrived in New York, in the 70's, at a time when rather than computers, border staff had volumes of photos of undesirables comparable to Brittanica, ahead of me in the queue was an Indian in nothing but a loin cloth, holding a cricket bat - don't ask me why. All the booths stopped and the queues got longer and longer whilst a circle of border staff debated what to do: Eventually he was led away to somewhere behind the scenes - a strip search would have taken 30 seconds!
