I wasted my time scrolling through all of that
Why did you give a link that makes no justification at all of your claim that there were two burglaries 'via locked front doors' in the weeks preceding Madeleine's disappearance ? ... why did you do that ?
You are creating a myth here, and that should be noted
I am not sure about the entrance point. But the exit point of person with Madeleine was not through the patio doors.
Why? Because, as Kate McCann mentions somewhere (when asked about Madeleine exiting on here own)..she found the garden door closed, the patio door closed and the long curtain behind patio door tidy.
A person holding a child could not do this, open the curtain, then the patio, then close the curtain, then patio, then open the garden doors and close them too..
IMO the exit was through the main ( front doors).. although there is a possibility that a person entered, given the Madeleine away though the window and then left alone.
