Sounds really weird and suspicious to me. They applied to have Madeleine made a ward of court only WEEKS after she went missing??? What normal parent would think of that, or if it was suggested to them, would even consider it? At a time when they were allegedly desperate to get her back, the McCanns made her a ward of court and literally 'gave her away'. But it's hardly surprising, because they had already given up on their parental duties and responsibities by neglecting her. However, that is a decision which could so easily come back and bite them on the backside. It only needs a judge to decide one of them is an unfit parent and then she might not be returned to them even if she IS found alive.
But it certainly sounds like another way for them to try and access the PJ's evidence against them, which seems to be their major concern. Why are they so paranoid about this? And any information on alleged sightings of Madeleine - which the PJ will already have followed up - will be passed on to their Spanish detectives. Do they honestly think Retardo 3 are going to find her? The same bunch of deFectives who KNEW where she was, who KNEW who was holding her and who PROMISED to have her home for Christmas? That's who they want to give this evidence to - allegedly.
The arrogance of this pair is beyond belief.
