Last night I mentioned the virtually impossible-to-believe Fox and Friends segment in which the News of the World was presented as another victim of a hacking episode, rather than as the perpetrator. If you haven't seen it yet, please: you owe it yourself to watch at least the first 90 seconds.

Here's what I missed: I'm grateful to many readers for pointing out that the expert who discusses the hacking menace with Steve Doocy of Fox is indeed an expert -- in corporate public relations. He is Robert Dilenschneider (below), former head of Hill and Knowlton and now head of the Dilenschneider Group, who recently was featured in an interview, "How to Manage a PR Disaster."

To Steve Doocy's credit, on first reference he introduces Dilenschneider as a PR expert. But through the rest of the conversation, the context and questioning are as if the guest's expertise were in hacking or data-security issues. Which is what I assumed on first viewing.

Thanks to many readers who, aware (as I was not) of Dilenschneider's eminence in the PR field, wrote to correct my impression. Many more wrote to ask whether his clients have included Murdoch or his businesses. I don't know; I've sent in a query today through the Dilenschneider Group's site; and will check with them on Monday.
