A case study in the manufacture of fake news is playing out right now in Melbourne. Victoria’s shadow treasurer, Louise Staley, is putting about suggestive questions hinting darkly at a cover-up of how Victorian Premier Daniel Andrews injured his back three months ago. She has not produced a shred of evidence to support this suggestion, yet the exercise has gained substantial traction in the media. All the main news outlets have had to pay attention to it. It is the kind of political chicanery that confronts responsible media with a dilemma: how to hold a public official to account without oxygenating the conspiracy theory in which she is trading.
