Rupert Murdoch is in real trouble.

On the important things, he has no recollection: Who had done wrong, who had committed blackmail, why their bosses didn’t do anything about it, and so on.

In just about each instance of this hearing, Murdoch answered those questions with some variation on, I don’t recall, I don’t know, I am not sure, and so on.

On the question of his knowledge of criminal wrongdoing at News of the World, for instance, Murdoch responded:

“I don’t know; that is what the police are investigating.”

At one point, the his cluelessness became so painful that his son, James, jumped in to save him. MP Jim Sheridan was having none of that, insisting that he speak directly to the boss.

That didn’t go too well for the boss. At one point, an MP asked Murdoch when he found out about a particularly acute case of wrongdoing at the company.

Murdoch replied: “Nope.”

Murdoch’s memory revived a touch when he was asked why he always had to enter the prime minister’s offices through the back door. He stated merely that that’s the way it went. “I was asked to enter through the back door,” he said.
