IMO this is a classic case of arguing about a completely irrelevant event.
Here is one fact which shows that the Smith sighting is irrelevant:
The child which all nine irish witnesses saw being carried was wearing a long-sleeved top.
Makes you wonder, then, why one of the Met's top crack detectives, Andy Redwood, made the Smith sighting 'the centre of our focus'?
Whilst on this issue I have to agree with ferryman that it really is obvious that Martin Smith is batting FOR the McCanns and not against them, and has been doing since January 2008, over eight years ago, I can't accept the Smith sighting as entirely irrelevant.
Highly relevant is the fact that in so many respects (I counted 17) the Smiths' descriptions exactly matched the ones given by Nuno Lourenco in his statement to the PJ of Wojcheich Krokowski allegedly trying to kidnap his daughter...which in turn matched the descriptions given hours earlier by Jane Tanner of 'Tannerman'.
Unusual, cloth clothes, beige/creamy coloured trousers, classic shoes, similar height, age, build etc. and also all using that silly phrase they used which really gives the game away that they were all working to a common script:
"Didn't look like a tourist".As if people can tell what tourists and non-tourists look like, walking about in the dark!
All these three sightings are a complete nonsense. I'm with that prominent former prosecutor and now child abuse expert Wendy Murphy, who said to a startled Fox News interviewer two years ago, on Scotland Yard's claims that Smithman might be the abductor, not Tannerman:
"I'M NOT BUYING IT'.
