I think it was described as insufficient evidence, not no evidence.
insufficient
ADJECTIVE
not enough; inadequate:
"there was insufficient evidence to convict him"SIMILAR: inadequate deficient poor scant scanty scarce sparse short in short supply at a premium lacking wanting paltry meagre niggardly skimpy sketchy incomplete restricted limited exiguous not enough too little too few too small
There was NO evidence arising from dog interlligence
There was NO forensic evidence
There was NO circumstantial evidence
In effect
there was NO evidence to validate the Amaral investigation's suspiciions.
Civilised societies do not conduct criminal proceedings of any kind under such circumstances. The kangaroo court of the internet can do very much whatever it feels like and who gives a tinker's curse about the impotence of that.
Quite simply - internet sceptics have failed in their prime objective of curtailing the funding of the investigation of Madeleine's case. And that is a very good thing as proceedings are under way to bring justice to victims of other crimes too many years after the crimes were committed, as a direct result.
