Oh no! If she thought she saw something she should have definitely spoken out. The point is that over 6 years her sighting was was the keystone of the abduction theory. Now no one is sure what she saw. Keystone gorn as you might say.
With respect - I don't see what the problem is.
JT saw a man carrying a child away - who IMO it was quite reasonably assumed - because of where he was seen and the time at which he was seen was very likely to be the abductor. Since then, for reasons which SY have not fully divulged to us, they now have compelling evidence that the man she saw was an innocent tourist.
This information means that the previous timescale can be discounted and a much longer timescale be considered for the abduction - and one which could solve the previous puzzling question of where the abductor was during those 'lost' 45 mins which - in the light of this new evidence - may now no longer exist.
Why would this be considered to be a 'problem' for SY rather than 'progress'.
