Court 7 contains a sealed dock – that is, the dock is surrounded by perspex on all sides – (if you wish to understand the significance of this, then research the 'four corners rule'.
Also, in the last video (pt 5) Darren stated that he:
was in the dock to be disregarded anyway, the Four Corner rule
If you think about it, it just doesn’t make any sense. He was arrested and kept to make sure he was put into the dock. Why would they then not want him there.
And, from the research so far, which did not take long, the opposite meaning is found to be the case. I think it's time that people show where they get their interpretation from. Seems to me everyone is just quoting everyone else on this without actually looking it up.
