That situation might well have been resolved had the third known person present in the locale been able to participate in the documentary, but it is unimportant because they saw no-one. But as pointed out on camera the putative positioning of Jes and Gerry was immaterial to what Jane saw as her vision of the important event was not obscured wherever Jes and Gerry had been standing.
Therefore the only witness to the unknown man carrying a child away from the direction of Block 5 was Jane Tanner who has remained resolute in describing exactly what she saw and exactly where and when she saw it.
DCI Redwood never identified anyone nor did he mention any direction of travel unless you can provide a quote showing he did.
But BO makes clear in her wit stat that it wasn't unusual to observe adults walking around with children in arms at night due to the fact a night creche operated.
Why would DCI Redwood, or any other police officer, identify Dr T? Surely to do so would be unprofessional hence DCI R refers to a British holidaymaker. We have no idea exactly what communication has taken place between DCI R and the British holidaymaker. If 'Tannerman' has been ruled out by the MET I wouldn't mind betting it was not only based on the location and time but also the physical descriptions and clothes matching 'Tannerman' and child. Now what would be the chances of MM's abductor also being in the same location at the same time, matching the same physical descriptions and clothes worn. Plus the s&r dogs did not track MM in that location.
Imo this whole 'Tannerman' sighting needs consigning to the bin.
