One of the most bizarre explanations for journalists spying on victims of crime and why Rupert Murdoch journalists at the News Of The World paid investigators to hack into the phone of a missing 13 year girl, of course it comes from a former editor of Murdoch's The Sun :
...there is a valid, albeit arguable, journalistic justification for it. If it is true, as alleged, that private detectives deleted some messages in order to allow new ones in, then any new message might have carried a clue as to the child's whereabouts and indeed our increasingly beleaguered police might have thought of this for themselves. The NoW showed some initiative here – it is only a pity they did so in such an insensitive and self-interested fashion, failing entirely to acknowledge the distress this could (and did) cause the Dowler family.These people are fucking insane.
