for one...you have said you have little knowledge of the case...and two....where posters are continually asking me for cites because they are not aware of facts i am posting.
I'm not up to speed with the minutiae eg whether or not the children had 1 or 2 ice creams but how would this help even if my case knowledge was at this sort of level?
This case really is simple to my mind. I know I keep banging on about it but imo its all down to the UNLOCKED patio doors. This narrows the field considerably as imo realistically it was someone who knew MM was home alone in the unlocked apartment.
Mass tourism to overseas destinations only took off in the 60's/70's. As far as I can recall MM is the only child who has disappeared without trace during all this time? The case of Ben Needham is different in that he disappeared outside on public? ground. I don't believe I would ever have left my children in hotel rooms etc but parents do but afaik it has always been in locked rooms with or without some sort of baby monitor or listening service. This is a world away from an unlocked door which the McCanns entered and exited several times a night allowing anyone with a knowledge of the doors to understand the doors were unlocked.
Everything else imo is a red herring: Tannerman, Smithman and all the efits in KM's book. Tannerman and Smithman were more than likely fathers collecting daughters from night creche. The efits were probably guys waiting for partners to do a bit of shopping in Barista or some other innocent event. If guys wanted to size up 5A they would do it discretely by walking past a few times and/or during the hours of darkness. They would not just hang around during day light. Note also none of the T9 observed anything remotely sinister nor did any of the other guests eg JW/BO, Moyes etc.
