I don't think so, according to what I heard they'll open a little abduction window and all that will grow out of it will be cut without pity !
Little birdies whispering in the ear of an amateur such as yourself is hardly going to fill us with confidence about your knowledge of the actual case.
You have no more idea than anyone else what this new line of inquiry really is and how important it may be.
Should the case actually be re-opened after this petition from the PJ to the authorities then we will know for certain two things. Firstly there is real and substantial evidence of abduction and secondly that both the PJ and the Prosecutors believe that evidence is sufficiently strong to justify a new inquiry.
And still we have not got a single sign from Amaral that he has a shred of evidence against the McCanns or surely he would have brought it forward to the PJ and got the case re-opened as a case against the parents? We will see the abduction thesis in the supremacy and the Amaral thesis rapidly waning.
