CORRECTION: CORRECTION: CORRECTION
I have only just noticed that because of some sloppy cutting and pasting the original blog on BP Oil Spill: Disaster, Media Hype or Fitting a Narrative? must have lost sense to the reader about halfway through (anything before that was really written like that!) Sorry about this but it is a lesson to me to read blogs through properly again and again even when you think you have already done so.
The new, edited blog is now available. The original incorrect blog has been deleted.
