Just skimmed through this. A few points:
We don't know if Maddie's dead or alive yet. We may have our own gut feelings, but that's all they are.
Maddie's parents clearly have friends in high places. (I believe, but am not positive, that they have a friend or relative who works for a TV company.) They have used their contacts to keep the profile of the case on the front pages. I see nothing wrong in doing that - I'm sure I would do it too. They're being hard-headed about things.
They set up a trust to collect the money that people sent to help find her. Better than just pocketing it. Trust funds can only be used for specific purposes, and to use the money for anything else is a breach of trust. Only the Trustees have power to spend the money, and, as far as I'm aware, the parents are not Trustees.
They also employed someone to go about raising contributions and public awareness, resulting in a trust fund of enormous size. They then used the money to pay for private detectives, and to finance trips to other countries where they thought they might be able to get a lead on Maddie's whereabouts. As Roman Catholics they sought the support of the Church and obtained an audience with the Pope. What's wrong with that?
I just don't buy into the idea that they used the opportunity of their daughter's disappearance to raise money for trips around the world. I'd hate to be travelling anywhere under those circumstances.
I also don't buy into the idea that they killed her and have decided to launch a huge publicity campaign to distract attention from themselves ... something like hiding in plain sight, perhaps. That's such a high-risk strategy. Too risky, in my view. Anyway, as has been said above, the parents are innocent until proven guilty. But being innocent doesn't put them above suspicion. I admit I am equivocal about them. But suspicions have to be based on facts, and the ones we know of aren't sufficient to point the finger of blame. Except in one respect ... the fact that they left their children alone! I think that's highly negligent and I am amazed the parents haven't been charged with neglect in Portugal or UK.
What's even more alarming is that the McCanns were with a group of other doctors/professional people and they had ALL left their children alone in their respective apartments.
If Ms Singlemum had left 3-year old Traci and little baby Brad alone in their council flat in Lewisham while she nipped down to the local for a quick drink and a packet of fags, and the authorities got to hear of it, the kids'd be in a children's home as quick as you like and Ms Singlemum would be facing charges of child neglect. But she doesn't have friends in high places.
