Plod asked Vodafone for phone records pertaining one individual, a journalist. What they received was a big list of a load of journalists phone records.
How does/did Vodafone know the occupations of their customers to the extent that they can say "Dear plod, here's a list of ALL of our journalists phone calls"? Upon what criteria did they collate the list? There's a lot more to this than meets the eye. It would suggest that their database is a more granular than one would otherwise assume. Just how much information are they storing?
