It was embarrasing to watch. At least Katter had the grace to ask the cameras and microphones to go out - Windsor was too keen on capturing the moment for posterity. Not a good look.

I suspect Katter got increasingly uncomfortably with the cameras because it was obvious he had no idea how to undertake due diligence on his own. The other two were asking all the important questions, and articulating arguments & debate while Katter was mostly silent or stuffing his face with food or unexplainedly walking out of rooms when people were talking to him.
