How do you know it wouldn't have happened if the McCann's had been asleep in the apartment? There was a man entering apartments, how did he get in? He assaulted children, all with the parents asleep in the apartments. He could easily have taken one of those children.
I thought we were here to debate how Madeleine disappeared, whether she was abducted, had an accident etc. what does repeating that the McCann's left the children alone bring to the debate? Nothing as far as I'm concerned.

Journ : As well as that line of inquiry, and the sighting by the Irish family of a man carrying a child, the police are also looking at a third important strand of their investigation.
AR : We have noticed that there was, between January and the time Madeleine went missing, a four-fold increase in the number of burglaries that were taking place in the vicinity.

Journ : In the three weeks prior to her disappearance, two incidents took place in the very block when Madeleine slept. In both, windows were used to gain access.
AR : Possibly, there is a scenario where Madeleine could have possibly disturbed somebody trying to commit a burglary.
Journ : To date, nobody has been caught for these crimes.
