OK the key factors to me are these:

Just before 10:00pm on the night of 03 May 2007, the Smith family from Ireland pass a man carrying a child in his arms. The man averts his eyes from them to signal that he does not wish to speak.
Four months later, during which time the McCanns never sought to exploit this potentially crucial sighting, the Smith family are watching TV. They see the McCanns return to the UK and observe Gerry leave the plane and walk across the tarmac with Sean in his arms.
The father, Martin Smith, is shocked. He recognises the walking style and the way the child is being held against the shoulder. It is exactly like the man he saw on the streets of Praia da Luz, four months earlier.
Back in Ireland, the Smiths watch the news and learn of Jane's statement and the suspicions falling upon Murat.
- The father contacts the Irish police. He tells his story. The man he saw was NOT Murat. He knows Murat and it was not him.
- The father is almost certain that the girl he saw was Madeleine.
Sept 2007, McCanns return to UK
- Gerry exits the plane, carrying his son against his left shoulder, the child's arms down along his sides, down the stairs and across the tarmack Gerry walks
- The Smith family see this recording on the news at 22h00 and are hit hard: they know this person, this way of carrying a child and of walking. It is Gerry McCann, they believe with a high degree of certainty, that they saw on 3 May at about 22h00, carrying a 4 yr old girl who appeared to be deeply asleep
- The father contacts the police to communicate this new information. He says he has not slept since 9 Sept and is very upset. It's as if he re-lived the night he saw the man carrying the child. Seeing Gerry walk and carry the child, awoke something in his head...
- Still not completely convinced, he watches the news again on ITV and also on Sky.
- No, there are no doubts. Gerry McCann looks just like the same person he saw carrying the child on May 3.
- Smith, upset and worried about what he saw and has concluded, needs the investigators to contact him.

The first eyewitness account of the frantic moments after Madeleine McCann disappeared can be revealed today.
Nanny Charlotte Pennington confirms that Kate McCann did scream: "They've taken her, they've taken her!"
The mother's precise words have become a pivotal issue in the case, with Portuguese police questioning why she would automatically assume Maddie had been abducted.
Mrs McCann's family have countered this by insisting they recall her shouting: "Madeleine's gone."
Miss Pennington, however, one of the first people to set foot in the couple's apartment after the disappearance, says she heard the mother use both phrases.

Prior to the PJ arriving at 12:40/12:50 Russell O'Brien has written the timeline for them all, including, "Jane tanner sees stranger walking carrying child." He does this while Gerry McCann sits at the same table.
At three o' clock in the morning Jane Tanner informs Gerry McCann for the first time, about the existence of a possible abductor.
Gerry looks horrified upon hearing this.
ETA. But why did Tanner feel the need to lie to the PJ, to put the time at three o' clock in the morning for when both McCanns were "first made aware" of the possible abductor.
Other than, I can only assume, in their way of thinking they perhaps thought it best that the McCanns appeared outside the loop, separate somehow from the conspiracy that they all were so actively engaged in. I'm at a loss here, I really can't imagine.
And not only that, just think about what we are being asked to believe. Madeleine has been snatched, don't forget Kate knew this instantly, Madeleine has been snatched, Tanner has witnessed a man carrying a child in the vicinity of the apartment just prior to Madeleine being discovered gone, and tries to tell us, and the PJ of course, that she waited five hours before she informed the parents for fear of upsetting them.
