The only way this guy can support his 'abduction by burglar' thesis is to accuse Jane Tanner of lying about the time of her sighting then? How can his theory be included in a thread about hard evidence then? He has none.
May 3rd. 2007: Jane Tanner saw the abductor carrying Madeleine at approximately 21:50 hours, in the street, near apartment 5A. The abductor trousers were described as “between beige and gold”. Surely it was white or similar, being the color perceived different due to street sodium lamps. Jane stayed at her apartment 5D and Russell returned to the Tapas Bar.

It has been a puzzlement why ... the window was open ... and the shutter was raised.
The most likely time for that to have occurred was after the last witness statement which placed Madeleine McCann sleeping soundly in her bed.
If you wish to discount witness evidence either because you have arbitrarily chosen which witnesses you will believe or because the statement does not fit the particular axe you are grinding ... be my guest ... but it is evidence nonetheless.
Heri has demonstrated exactly the method that could have been used.

His hypothesis explains a lot and makes a nonsense of the accused 'staged' scenario.
(a) demonstrates method
(b) demonstrates time taken
(c) demonstrates no entry was required
(d) demonstrates that the burden of the child could have precluded closing both window and shutter
Anyone with an awareness that burglaries had been taking place where ingress was via a window, two of which had occurred in the same apartment block as the one from which a child had vanished, would I think have taken that on board to arrive at a different theory from the one which drove the investigation.
