When I said Tannerman had been eliminated I was jumped on from all directions and told that it was not DEFINITE that the tourist was the man JT saw and that was NOT what SY had said - and that SY were NOT 100% certain. If that is the case then any further information regarding this tourist could be helpful to SY to confirm or otherwise their present strong belief that he was the man JT saw.
Seems sensible enough to me.
How could they be certain that Ms Tanner, considering she saw a carrier at that time and place, saw Innocentman ?
Nobody can, not even Ms Tanner who has a blank on the face topic.
What DCI Redwood is certain of, however, is Madeleine wasn't abducted at the time suggested by Ms Tanner. In fact there was no need to suppress Tannerman, DCI Redwood could just put him at the back of the scene and bring Smithman to the front.
But he gently killed Tannerman. I feel he'll never resurrect him.
