We have no idea what the Portugese police may have, or not found, Anything you may or nor4 belive is press speculation.
Anecdotal statements are just that, the fact that the press choose to print it as fact, should be taken with a pinch of salt.
Why is it wrong for the Police not to make information available? If they did and it costs a future court case, what would happen. What if those files point the finger at the McCanns, what would you say then?
I don't think the portugese can be called incompetent, its always the same when a Brit is involved in a crime abroad, if its nor solved the locals are incompetent, don't care, can't be bothered etc however when they do solve it they are just doing thier jobs.
Stand back a second you are called to an hotel room there is blood a missing child but two other children are fast asleep untouched. Try to think in isolation, what would you as a layman. never mind a trained policeman/woman, think?
I don't think it will cost millions just a couple of salaries, but I bet they can do ant better and never could.
They sent a "task force" to greece to look for Ben Needham, I don't know what happened to Maddy and I suspect we never will.
