With all due respect to any and all on this board, I have been a business and technology journalist for more than 30 years. I've interviewed every major and not-so-major figure in information technology from Bill Gates to Steve Jobs and everyone in between back and forth a hundred times. Good and thoughtful journalists (and there are many of us out there) abide by but a few ground rules: 1) Never ask a question that you don't already know the answer to, and I mean never. You never want to be surprised by an answer because it inhibits your ability to guide the discussion and shows you haven't done your homework--there's no faster way to get a public figure to lose interest in talking to you; 2) As Jake alluded, ask twice (maybe a third time if you rephrase to come at it from a different angle) but move on if your subject declines to answer. Years ago Jim Gray blind-sided Pete Rose in an interview and his career fell away soon after to nothing. He deserved it because he made himself the story; 3) Your subjects may be friendly to you, and they may even be your sources, but they aren't your friends and you're not their friends; they are public figures who make news and your job is to get their perspective on the news they make. There are lots of pieces to the truth, not only the subject's version makes the whole story. It is Katz's job to piece together the truth from all angles and JB's option to add his perspective, if he so chooses; 4) Your loyalty is to your readers, not to your subjects and certainly not your employer, even though your employer signs your paycheck. That's the essence of the fifth estate--a fealty to the public to know the truth. True, your employer pays you but their interests very often collide with the public's to know the truth. As a journalist, you must remember that your job is to inform the public of your best version of the truth, that's your only sense of loyalty; 5) No good publicist, and I have dealt with thousands, tries to set boundaries about what his or her client will or won't talk about; instead a good publicist makes sure beforehand that the reporter has a full understanding of what the subject wants to talk about, realizing, as Jake said, that a public figure cannot dictate what he or she is asked, only what he or she is willing to answer.
My guess in this case is that JB served as a source for Katz in the past on matters Big East related, he expected some loyalty as a result and didn't get it when Katz badgered him for Fine answers (grandstanding all the while probably to please his editors and not look soft on the story) hence JB's sense of betrayal. Chances are high that Katz's editors pressed him to nail Boeheim, figuring there was a story there. Katz followed suit and Boeheim was understandably tweaked.
All due respect to CTO's version--and maybe she has inside info to base it on--but JB has been to this rodeo many times and it's hard to believe he didn't understand that he can't control the questions he's asked.
