In Portuguese law, as in English, truth is an absolute defence.
In English law, implicit untruth can be libel as well as explicit.
I don't know about Portuguese law.
But this statement of Amaral's from his book is actually contradicted by what Amaral himself says before in the same section, and is certainly not true, as we know having seen the video ourselves:
Eddie did not hesitate for a moment. He was only interested in the McCanns' automobile. No other attracted his attention
Goncalo Amaral,
I don't know the detail of the incident you have brought up, but it is an example of what has been totally absent in this trial ... direct rebuttal of the claims Amaral made in his book, proving them false ( libellous )
It is what I thought would be happening in this trial ... the McCanns 'proving' that Amaral lied
They have not
The entire case has been about how much damage the McCanns suffered as a result of Amaral's book ... but with no protestation made, or proof offered, that he lied about anything
