Stop changing the subject... The PPs did NOT say Madeleine was abducted as Ferryman says. deal with that first before you bore into Amaral
The PPs said abduction was one of several scenarios, not the only scenario.
In TTOTL there is only one conclusive scenario after the application of selectively edited circumstantial evidence, despite many pointers to the contrary.
Pegasus asked if there were grounds under the FMF objectives to pay for the legal action against Amaral, and I have explained why I believe there are valid reasons.
Amaral chose to make himself a spokesperson for the original investigation by writing his book. The Portuguese Justice system did not distance itself from his opinions by prosecuting him for breach of secrecy, therefore we must assume they supported him.
The McCanns couldn't sue the whole of the Portuguese Justice system
for the failures of the original investigation, but they could take action against the very public actions of a citizen who has always said he knew far more than he has ever disclosed about Madeleine's disappearance.
