The fact that the McCanns agreed to go along with the Crimewatch program, in which DCI Redwood presented his case, strongly suggests they accepted it at the time.
The fact that DCI Redwood was not convincing enough for some does not alter that fact.
And being 'convincing' was not his aim. His aim was to examine the facts and make a public appeal - not give the public an explanation or justification.
I agree
DCI Redwood told the public that Scotland Yard believe that Jane Tanner almost certainly did
not see Madeleine being abducted
The McCanns, appearing on the same TV program, expressed confidence and renewed hope in the progress Scotland Yard have made
The conclusion, therefore,
must be that the McCanns accept that the man Jane Tanner saw was not involved in Madeleine's disappearance
So why have they not said so ?
Why have they not expressed frustration and despair that they ( and their hired private detectives ) have spent years looking for the wrong man ?
... and why are they still promoting the Jane Tanner photofit on their official website, asking people to come forward to identify the man ?
