As to interviews, Panorama.
As to the rest of your post the Met had every opportunity to ‘protect’ the McCanns from trolls when the dodgy dossier was handed to them yet did absolutely nothing. What does that tell you ? OG has been reviewing and investigating the case for 7 years now and for those 7 years there has been questions about the amount spent on it and yet the interviews have still taken place. Why do you believe that this year OG suddenly became sensitive to the online noise? Why this year have they suddenly become sensitive to the McCanns feelings ?
Sorry, was there a Panorama about Jane Tanner? I must have missed that. There was a Panorama in which she contributed her first hand account of the sighting, but I don't recall it being all about her and her feelings - has she been in the habit of telling all to the media since 2007? I don't think so.
As for the Met, I'm not talking about them protecting the McCanns per se, just not encouraging the online hysteria about the amount being spent on Op Grange. It's hardly in the interests of the investigation or Madeleine or her parents to have so much negative chippy sanctimonious online harping on about it, hence why this time, unlike other times, there was a reluctance to divulge the amount being spent. In any case who knows what threats the McCanns may have recently faced as a result of previous media appearances, perhaps the Met really do have their best interests at heart and have advised them that a lower profile is in the interests not only of the investigation but their own and their family's safety.
