I am of the school that still gets irritated when interviewers fail to greet their guests with a good evening - and cut them short at the end of the interview without allowing them to say a civilised goodbye :)
The sequence of events, stemming all the way back to the failure by Newsnight to air a report on SoVile, through to the allegations of abuse carried out on BBC premises, and then on to the management and checks of a partially outsourced investigation carried out by the BIJ point to some serious issues with the editorial chain of management.
As to whether or not the last investigation specifically mentioned Lord McAlpine - it didn't, although the BIJ head boasted on twitter on the 24 run up to airing the show that it was to name and shame - There were sufficient clues aired in the report that media types and others could narrow the speculation down to essentially 1 individual.
So Entwhistle, new to post, but 20 odd years at the BBC, had to handle the fallout - and unfair as it might seem, he fumbled the ball. The most curious aspect of the whole affair was his lack of curiosity.To be unaware of the content of that second broadcast Newsnight investigation is simply incompetent.
And once an organisation becomes the story, obscures the underlying investigation into child abuse, his position had become untenable.
And for those claiming some sort of cover- up, or that the original investigation is now buried? How so? All the enquiries that have been set up are still in force, and will be carried out, and will report in due course.
The tabloids and the murdoch press will no doubt relish the turmoil within the BBC, and publish pieces critical of the BBC, but most observers will recognise that and discount the obvious bias I think.
