I just don't understand your obsession with them not phoning themselves, or why you think they should have known the number.
Eleanor, this is not an obsession, just an observation.
When you need to be sure something's done properly, you do it yourself, a fortiori if your child's life is at risk.
I don't know if they knew the european emergency number or not. You don't as well.
They had cell phones, a tool that finds its justification mainly in cases like this one, since it allows some one whose child is missing to send an alert in the seconds that follow the discovery. Had they done this, the PJ, not the GNR, had been there half an hour later.
I'm not blaming Mr and Mrs McCann, Eleanor, I can understand their behaviour. But I'm not letting you and others go on accusing the Portugueses of all the discrepancies, if not of being guilty through incompetence of Madeleine's horrible life away from her family.
