The McCanns could have used the money in the fund to buy advertising space in the Portuguese newspapers to publicise the efits. As to Amaral, do you really think he had any control of editorial decisions just because he wrote a column for the paper ? Besides he always thought that Smithman was a very important lead.
There's no way of knowing whether they could legally do so or not, or if they could, but made a conscious decision not to, and if so, why. Were they advised not to? If so, by whom?
I never said that Amaral had any control over editiorial decisions. However, CdaM is (or certainly was) about as neutral as Julia's pink couch. Why would it haved wished to a) upset a cosy relationship or b) potentially confuse readers?
Yes, he did think Smithman was an important lead. With numerous hints over time (by various people) as to whom he was thought to have been. If there had been a conscious decision not to publicise them at the time, it might have been to avoid the similar ridicule that Jane had been subjected to.
Aside from that, there is still the issue that there was no active investigation to follow up on leads and to request any action that would have required a court order.
As to copyright that belonged to the fund or they would not legally have been allowed to pass the efits on to the PJ and Leicestershire police.
I'm not sure about that as copyright law is complicated. If whoever was involved in producing those efits hadn't been paid, who owns the copyright? What were the terms of the contract? Was the contract drawn up under UK or US law?
I don't know who passed the efits to the PJ / LP. Was it someone from Oakley? From the Fund? Was a court order issued to obtain them? If so, at whose instigation?
Your last paragraph makes you wonder why the McCanns even employed PIs if there was such an issue with any evidence they uncovered.
If PIs were never of any use, I don't see the point of the profession. We don't know at the moment whether any of the leads have been helpful to the review or not, so hard to tell.
