There was definitely something fishy going on at the FSS. Scientists appeared to have been telling Portuguese investigators one thing off the record and another in formal reports? The PJ made the mistake of acting on what they were told in good faith, they must have been shocked at what came later.
This is plain wrong, John, disinformation spread in Amaral's book.
John Lowe wrote an
explanatory email (inaccurately referred to by Amaral as a "preliminary report") to Stuart Prior
about a particular result (from the boot of the hire-care).
He said that there were any number of (possible, and
innocent) explanations for the
possible presence of Madeleine's
DNA (distinct from Madeleine herself!) in the DNA mix from the boot of the car.
Secondary transfer (of Madeleine's DNA) from items of Madeleine's (clothing etc) carried in the car might be one.
Having established that Madeleine's
DNA might, indeed, be in the mix (for wholly innocent reasons) Lowe contented himself, in his one-and-only report, in saying that a result from the boot was inconclusive.
Amaral incompetently misinterpreted that as the FSS
changing their minds and
bottling out (of the implication that Madeleine might have been transported somewhere dead in the Renault).
Amaral libelled the McCanns, John Lowe and the FSS in a single fell swoop.
Unbelievable.
