The mccanns have claimed to be searching.
It isa up to the mccanns to prove they have, and not Angelo to prove they haven't.
I would have assumed that the penny might have dropped by now that the Policia Judiciaria and Scotland yard are searching for Madeleine McCann.
An action which has come about only because of the exhaustive efforts of her parents to have her case reopened ... efforts which have been questioned, vilified, criticised etc. etc.
Who is going to suggest that is not a more effective course of action than prowling the streets of Luz ... knocking on the doors of people who,like Shining, very likely were not resident at the time ... demanding ... " Excuse me, I wonder if you would mind terribly if I invaded your home to 'look for' my kidnapped daughter ... what do you know about it ... when did you have that patio laid ... you won't mind if I dig up that flower bed ...???"
Hmmm ... not terribly sane, is it?
The abuse directed at the twins does not emanate from their loving, caring parents ... it is born of downright hatred for a family who have suffered greatly ... but are seen as fair game because they have risen above that to move heaven and earth to find out what happened to Madeleine.
Perhaps the motivation for that hatred should be given some self examination.
