The funny thing is that whenever a story like this emerges, people are still talking about "crazy conspiracies." As if to suggest that anything that is not absolutely public, transparent and conceded out loud is simply unthinkable. Even after a story like this begins to surface. The press had carte blanche to eavesdrop on citizens with the help of the government as long as they shared any information. Again, governments working with the lowest rungs of the criminal underworld to persecute their own citizens in a squeeze play in the middle.
I'll venture a guess this is the reason Murdoch is shutting down his entire operation ahead of any legal action. He doesn't want people following this thread of inquiry down the rabbit hole. I'm guessing it leads straight back to the source of all evil in the world.
