because the book can only be libel if Amaral lied, and we know he didn't ...
Then what is the explanation of the extraordinary discrepancy between Amaral's depiction of Harrison's role in the investigation and Harrison's actual role?
Amaral, in his book, accused the McCanns of some serious crimes. He cites the Tavares interim report in support of these. The Tavares report has been superceded by the final statement of the prosecutor.
As you say Amaral has also been rarher selective in a number of other areas, such as his reporting of the Harrison report, and other areas.
To accuse another of crime is potentially defamation. Fair comment and truth may provide a defence.
It follows that the McCanns have a case against an ex policeman who accuses them of committing a crime without that crime being proven.
