I'm not going to strain any ligaments defending Johann Hari - he just reminds me of what people say about his newspaper, The Independent: "The Daily Mail for people who recycle."
Hari just strikes me as a corduroy-jacketed version of John Gaunt. Massively overconfident in expressing poorly thought-out opinions.
Still, he's hardly unusual within his own profession in that respect, and his journalistic colleagues seem to be prepared to cut him a bit of slack for doctoring his interviews. In a lot of cases, I can't see that a pedantic sticking to verbatim quotes is all that important.
I reckon a spot of community service is more appropriate than ten years hard labour for what he's done here - but there are plenty of other people arguing about that elsewhere.
Anyhoo.... I quite like the idea of 'underarm interviews' - where the interviewer and interviewee collaborate - each editing their questions and answers intending to help each other refine the questions and answers: Stripping out the problems caused by inarticulacy or imprecision.
I did one some years ago with Chris Dillow here - I learned a good deal more about what his position was than I'd ever have got from reading his general writing, or any live interview that we could have done. We did it just updating a Google Doc - often revising an earlier point to help clarify the current one.
I think it worked well - both sides of the table have nowhere to hide. I wish there were more of them. Almost 'set piece' interviews.
