Let’s start with point one. This is not the PJ, who were the victims of a horrendous smear campaign by, as you now admit, people close to the McCanns and this is not Portuguese money that is being spent on the investigation. If they expressed their displeasure at this point, even through a third party, can you imagine the backlash ? Public money being spent to fund an investigation by, arguably, the best police force in the world and still they’re not happy. Even the most ardent of supporters would find that hard to justify.
Second point, what is to be gained by making statements of gratitude? Time. Just as in the first investigation when the McCanns were telling the world that everything was fine and they were working well with the PJ, even when their house was being searched and they were being told by the PJ that they believed that they had a part in their daughter’s disappearance. They knew eventually the truth would come out. They may be using misdirection again to postpone the inevitable.
Third point unless you think OG is leaking suspects like a sieve then a full-scale propaganda campaign is already underway to undermine their credibility.
I think you're in danger of boring me into submission now! Taking your points in (brief) reverse order as I have to get to work now
1) I neither believe OH is leaking like a sieve, nor thst there is a full-scale propaganda campaign against OG, in fact I find that suggestion utterly bizarre. Who do you believe is behind this full scale propaganda campaign? Surely not the McCanns?
2) they are buying time by getting Clarence Mitchell to express gratitude to the police?? That makes little sense to me either, sorry. Why do they need to get Clarence to express gratitdue and what difference would it make if they expressed it "directly" as you insist they haven't?
3) I'm trying to imagine a backlash any worse than the backlash they have been through for the last 11 years. Nope, can't imagine it. By now, I should think the McCanns could cope with any backlash and if they genuinely believed the tide was turning against them again then they would get greater mileage out of expressing their concerns now rather than their gratitude about the investigation.
But that's all a matter of opinion -you have yours I have mine.
