I agree with Brietta!
Logical isn't it ... and we are both sometime logical thinkers.

Borne out by the fact that neither Dr McCann was charged with any offence in relation to their daughter's disappearance ~ there is not a shred of evidence linking either them or their friends to what happened to Madeleine.
That leaves wandering off ... or abduction.
There is no evidence that Madeleine wandered off.
Whether members like it or not there is evidence that there had been an intrusion to the apartment. Dr McCann's statement to how she found the apartment window on her return is evidence.
Ever wondered why Sylvia Baptista's assessment of the situation has carried such weight in the doubters' lexicon ... her suspicions when Dr McCann requested pastoral support have become legendary ... but no-one mentions that she also claims to have seen Robert Murat ...

She doesn't remember who was with him, whether he came walking or in some vehicle. That same individual, she was told later, is the son of Morat, his first name is ROBERT.
Robert speaks fluently English and Portuguese. He helped the GNR of Lagos and later the PJ, translating the testimony of some British persons. http://www.mccannpjfiles.co.uk/PJ/SILVIA_BATISTA.htmSo it is very much a pick and mix of which evidence internet detectives will choose to illustrate their point or their prejudice ... fortunately, with the eyes of the world on Madeleine McCann's case the rule of evidence and therefore the rule of law had to be seen to be being applied.
