I fully understand the point that my hon. Friend makes. On one occasion I attended a demonstration outside No. 10 Downing street, when the Brazilian president was on a visit, and the police were taking photographs all the time. I asked, "Don't you have enough photographs of me without taking any more?" I do not know whether that photographer was in trade or business, or whether he was selling the photographs, but I suspect that he was putting them on file. I cannot understand why they needed more photographs of me, and apparently they were hounding my hon. Friend at the same time.
