Reporting from Newcastle Crown Court
Mr Knox is standing with one hand in his pocket and a sheaf of papers in the other.
He peers at a piece of evidence on the screen in front of him, then back up at Adam Carruthers on the stand.
Occasionally he leans and rests his weight on the bench, as he puts his suggestions to the defendant.
The members of the jury have a screen between each two of them as they follow along, examining the maps and images being put in front of them.
