Craig Murray nails it.
By their own admission, the Murdochs’ media empire is too large for effective corporate governance. The fact that Rupert, James and Rebekah claim they had no idea who authorised thousands of illegal phone hacks, and had no idea who authorised tens of thousands of pounds of bribes to policemen, and still say they have no idea even after all the hullabaloo, is positive proof that such concentrations of media ownership become unaccountable and should be banned by law.
They are condemned from their own mouths, by the line of defence they have chosen. Whether it is true or not doesn’t matter in terms of the policy that must be adopted – the prevention of multiple media ownerships.
