A telling moment in the Murdoch hearings went down at approximately 4:26 BST. James Murdoch was under intense questioning from whip-smart MP Paul Farrelly, who was concerned about a key document relating to News Corp.’s knowledge of its own wrongdoings.

James Murdoch did okay in handling Farrelly’s insistent and detailed questioning.

Then Farrelly asked Rupert Murdoch senior if he was aware of the document.

“No,” came the answer from Rupert Murdoch.

The a little confusion stirred, and it became clear that Murdoch senior had no idea what document he’d just disavowed.

The moment shed insight on Rupert Murdoch’s marching orders: Deny all knowledge. You’re the chairman and CEO of a company with $32 billion in revenues.
