As noted:
1) Jane Tanner identified a man who has now been 'almost certainly' identified by Scotland Yard. He has been ruled out. On that you can choose to believe Scotland Yard or Sadie. (See previous page; Crimewatch documentary 2013)
2) Jane Tanner -- look at the national C4 documentary Madeleine Was Here/image I provided -- along with Jeremy Wilkins corroborated that Gerry McCann was within two metres -- or for arguments sake, in terms of time, 3 seconds -- away from the gate of 5A. (See Channel 4 documentary available on YouTube, and Jeremy Wilkins' statement and drawn map).
3) Jane Tanner's memory improved to the extent that she went from being unable to identify the man she saw by his face to eventually identifying a man via a facial photograph. Tim Craig Harvey, a man who was paid by the McCanns to look at the case, confirmed the second of those facts in a national C5 documentary entitled McCanns And The Conman. I provided a documentary, produced by Channel 5 -- and people can judge for themselves.
For anyone other than Brietta or Sadie--- you can access the following resources on the previous pages of this thread, and you can decide for yourself. :)
