Barclay seems to think that the two marks on the exterior of the shutter (36:51) were made from the inside of the room. I think they were maybe made from the outside.
For its time the Dispatches video presents the very clear, concise and unbiased opinion of experts who have approached the problem in an analytical manner and worked through the problems step by step.
They have come to some very interesting conclusions despite not being in possession of all the facts since at that time much wasn't in the public domain and they were not allowed access to the McCann apartment.
For example ... they obviously did not know that it was possible to raise the window shutters from the outside thinking the internal mechanism was the only means of doing so ... or that the witnesses had interfered with the shutters.
I think Dave Barclay also mentioned lichen on the cill.
36:58 "They're not two thumbs are they?"
"They look thumby"
"Is that from the outside ~ and trying to push it up? but you would never do that with those shutters because they've got a ratchet handle"[/b]
From 39:40 some very valid points are made about claims which Dave Barclay finds "almost incomprehensible"
40:31 " ... so we should just wait and see what the results show. It's not beyond the bounds of possibility that they will completely exonerate the McCanns."
I wonder what type of conclusions might have been reached had the experts had access to the police files and the final report from the FSS?
The programme as a whole and in particular the summing up at the end gave one a glimpse of how different the approach of a British investigation would have been and the different outcomes which might have been achieved.
One thing which I believe would not have happened would have been the deliberate demonisation of the Drs McCann.
