Why were you interested in the tree?published at 12:42 British Summer Time
Mr Carruthers is now being asked why he shared so many snapshots of social media posts and media reports about the felling with his co-accused the morning afterwards.
He says he woke up to find the news "all over Facebook", adding it was "everywhere".
He says: "My understanding was it was just a tree.
"I couldn't understand why everyone was sharing it. It was like every second post was about this tree, I just couldn’t get my head around it.
"The way it was travelling through the news, I was amazed how something so small could create so much publicity."
Mr Gurney asks: "Did you have a fixation on that tree?"
Mr Carruthers replies: "No, not at all."
