I'm losing the plot completely here. Shining has a theory that a pre-planned abduction may have taken place. She suggested three components to her theory.
1. Weak security as in keys, hence the discussion about who would be able to have a set cut.
2. The MW booking system offering details about children's ages which weren't shown on other booking systems. Hence the discussion about who could see the details and whether the system was actually significantly different.
3. Control over allocation of apartments. I haven't as yet been able to discover the advantage of having this control.
I think perhaps a new thread to discuss Shining's theory may be needed, as it's not a botched burglary.
While this particular theory is not botched burglary, the two overlap considerably.
Botched burglary - explain open window and raised shutter.
Planned abduction - explain the same.
So let's focus on botched burglary. Someone transferred the McCanns from OC reception to 5A. Two drivers, one fairly young and one (cough) somewhat older. A question the McCanns could answer easily. A stone unturned.
The younger driver can be established as living close to 5A, and in Heri's latest visit, we went to the top level of LuzTur. Confirming that from this public area, one can observe the whole of the rear of block 5.
This is what theories are made of. Plug in some facts. Plug in some analysis. What you get is - what you get.
