Britain's Metropolitan Police -- Scotland Yard -- which has come under increasing criticism for its handling of allegations that reporters working for the Rupert Murdoch tabloid News of the World had intercepted voice mail messages of politicians and celebrities, has asked one of its chief critics, The Guardian newspaper, for any information it has about the matter. In reply, Guardian editor Alan Rusbridger said that all of the important evidence it has uncovered "is sitting in your own files" including transcripts of voicemail messages left on the phone of Gordon Taylor, CEO of Britain's Professional Footballers Association. (The Guardian had earlier reported that Taylor was one of three people who had been paid $1.5 million in settlements in an effort to contain the hacking scandal.) Rusbridger said that the Guardian had come up with the information in its Hackergate stories by interviewing numerous reporters who had worked at the News of the World at the time. He suggested that Scotland Yard do the same. He also criticized The Police agency for cautioning former NoW reporters that anything they say about the case could be used against them in court -- "treating them as potential defendants as opposed to potential witnesses."
