Did Amaral's book really damage the search for Madeleine McCann?

[G-Unit]

Found wanting how?

The book was published after the investigation was shelved and so the book cannot have harmed the investigation.

I wonder why the McCann's lawyer included that point? They did say in 2010;

They said there were cases where their investigators had passed leads on to the Portuguese authorities and Leicestershire Police, their local force, only for them to be ignored.

I wonder if they were referring to those 'Smithman' e-fits?

11. Because of the statements made by defendant Gonçalo Amaral in the book, in the documentary and in the interview to Correio da Manhã, the Polícia Judiciária stopped collecting information and investigating the disappearance of Madeleine McCann?

       Not proved.
