Petty nitpicking IMO. Whether parents choose the listening service or choose to mirror it - the practice is the same. i.e. parents choose to leave their offspring asleep in their room whilst they go to dinner - knowing that regular checks will be made.
IMO the same people would not dream of doing the same thing at home. However people do have a different mindset when on holiday - they are far more relaxed and don't spend their time thinking about tragedies which might befall them - and they are surrounded by people who are similarly relaxed and enjoying themselves.
The fact that the Listening service is offered by reputable tour operators etc is enough psychologically to reassure their clients that this method of childcare is safe as if would not occur to them that they would be offered a service which would put their children in danger. A couple of the McCanns friends had used this service before with no problems - so even more reassuring to the McCanns that it was OK.
From memory but IIRC MW have ceased offering this service - giving their reason that they do not wish to lull people into a false sense of security. IMO that is exactly what happened to the McCanns.
I expect Mark Warner had to face the undeniable truth that listening services don't safeguard children from danger. If you think holiday companies offer them because they're safe and not as a good marketing ploy you're very naive. Intelligent caring parents make their own minds up about the care of their children and leaving them in an unlocked apartment in another country isn't something most parents would dream of doing these days. Even stupid parents are capable of working out that children can wake, cry, wander, climb, fight, choke, play with knives, etc. Were the McCanns really so stupid that none of those possibilities occured to them?
More repeats of the unfounded allegations;
"British police have revealed Madeleine may have been snatched during a break-in at the apartment where she was sleeping".
What did they say then?
