It means to me that she isn't as daft as some might think.
Only statements can be proved or not. The damage done to The McCanns can only be an opinion.
Well she is armed with an Appeal court verdict stating that the book was a logical interpretation of the facts.
Then in terms of damage done it is entirely quantifiable in terms of measuring the impact of the book's message through the circulation of its contents through media outlets.
Yet none of the the McCann witnesses offered any statistics about the number of negative articles produced as a result of the book's launch. Why don you think that is?
Although if a previous court argues that the book does not offend the McCann 's rights as the starting point, then surely the impact of said book should not be of any consideration.
In another words if a PT court has ruled the book as legitimate in terms of its contents then how can its impact then lead to libel?
Either the book is libellous and should be banned (which it wasn't), or it's not libellous and ok to be sold therefore the impact of its message makes no difference because in the first instance it does not offend the McCann's rights.
