Ok SM...
Mrs. Fenn was referring to the night of May 1st when she reported hearing what she thought was Maddie crying.
We do not know if the 1.5 hours without adult supervision was "typical" or just that night. The T9 tell us they checked frequently. We have read reports that the waiters at the Tapas bar said no one (except RoB) left the table that night until Kate did her check.
Once again, it is a matter of looking at the big picture rather than dissecting one single incident and making it fit into your theory. I have read many articles, reports, rumors, speculation, etc. that indicate that the McCanns were less than vigilant on their holiday. I have seen the evidence of them leaving the twins in the creche in the days following Maddie's vanishing. I have not seen a single report, article, rumor, etc. that confirms what the McCanns and the T7 have said. In fact, with all the checking that was supposedly going on it is a miracle that no one called LE to report all the people in and around the apartment that night.
When it comes right down to brass tacks people, the McCanns have freely admitted that they left those babies alone, even after Maddie complained, and therefore, in my opinion, are capable of very neglectful behavior. I believe they did not give a chit about anything other than their own enjoyment. The preponderance of the "circumstantial" evidence d a m n s them. IMHO, of course.
Monday will bring a new day. The world's press will have access to the completed dossier. Let's watch and see who has the "big brass one's", eh?
Did that help/answer? I can go (as my baby girl loves to say) search up some more stuff on the internet. Let me know.
