If new evidence comes to light, then I assume that will influence the direction of the investigation and any prosecutions that follow.
However, as things stand, there is no credible evidence to suggest that the McCanns are guilty of anything. And I think we all know that you dont believe there is any evidence of an abduction etc etc...
But - a little girl is missing, a witness saw a child being carried in the viciniti at ablut the right time, and the supercop who co-ordinated the investigation ruled out entry or exit by the front door because "nobody was authorised to have a key" (ref: TV1 Documentary), and the crime scene was so badly handled by the Portuguese police that it is hardly surprising that there is no evidence of an intruder.
By insisting that there was no abduction, you are saying that the McCanns were involved in her disappearance.
So I suggest we all take it as read that Stephen2500 does not think there was an abduction, and then you can stop trying to derail any threads which discuss such things as the "A" word.
