It's an unjust world IMO where an ex-cop can legally base his damning, accusatory book on an unsubstantiated reading of the evidence which results in the parents of a missing child being falsely accused of all sorts of heinous acts.
I watched (most of) the Leveson enquiry at the time. Re the McCann episode, all (?) the journos stated that the leaks came from the PT police. Although not specified, few could logically have come from the GNR as they weren't privy to the investigation files, AFAIK, and therefore I presume that "police" meant the PJ.
The McCanns could never have nailed specific individuals in the PJ as the source of the leaks... how? The PT tabloid / PJ blitz against them that started as soon as they became arguidos was relentless. By the time Amaral's book came out, he was a "private citizen", but the vast quantity of leaks meant that the arguably most damaging ones about the McCanns had started before his publication. Nothing to do with me, mate.
