There were people there who have testified to what the dog did or didn't do.

As they walked down the path, they saw Luke Mitchell, also carrying a torch, coming towards them. The four of them plus Mitchell's dog then started to walk back down the path.
Janine says Mitchell went through a V-shaped gap in the wall. She adds: 'We heard Luke shouting there was something there or he had found something.'

The court was convened in an area covering the wall and the break in the wall leading to the deposition site where Jodi's body had been left. I would imagine that Mitchell's version of events was heard along with that of the three other witnesses.
It was obviously considered to be an area of paramount importance since it was deemed necessary to construct a replica wall in the courtroom.
If we had to have been there to discuss particular aspects of this or any other case there would be no blogs - no social media and no fora such as ours.
From what I have witnessed and read ~ that might indeed be no bad thing.
‘ Cross-examining Janine, Donald Findlay QC says: 'The fact of the matter is, the only person who showed any interest in checking behind the wall was Luke.'
Janine replies: 'Yes.'
Donald Findlay reads a statement given by Janine to police in the early hours of July 1 in which she said that 'everyone was in hysterics'.
Under cross-examination, Janine says: 'The only time Luke showed any emotion was when he was on the phone to the police and we started shouting at him and then he started to raise his voice.'
Findlay asks: 'Are you saying the police have written something wrong in the statement.'
Janine answers: 'I may have phrased it wrong. They may have taken it down wrong. I didn't mean everyone was in hysterics.
'As I said, the police have misrepresented it.'

Let us not forget that JaJ would have read the statement she made to the police and signed it as a true representation of what she said.
