The Christchurch attacks shocked the world and many people found themselves switching on the TV news to better understand what was going on. But how does this affect your mental health? The more footage you watch, the more likely you are to experience psychological distress, explains Richard Bryant, especially if you’re watching from the gunman’s perspective.
And in the aftermath of the attacks, writes Denis Muller, there is an ethics lesson for the professional media, many of whom failed the “test of necessity” by broadcasting the violence. Whether social media published it or not is immaterial, Muller argues – the weakest reason for publishing something is that someone else already has.
Meanwhile, autonomous transport is coming our way, but we do have a choice about what form it takes. Peter Newman argues “trackless trams” are a better bet than driverless cars to give us people-friendly cities.

The difference in the Christchurch attacks is that propaganda supplied by the perpetrator was available to the professional media, even as the story was breaking.

Cities have a choice of autonomous vehicle futures: cars or mass transit vehicles. Which one we adopt is likely to determine how people-friendly our cities are.

Autonomous mass transit vehicles like 'trackless trams' are a better bet than autonomous cars to give us people-friendly cities that capture the value created by infrastructure for the common good.

When the media genuinely behave badly, this should be called out by politicians. But doing so through the courts is not a good idea, nor conducive to democracy.

When a sound is made, it spreads. And when it hits a hard surface that is far away, it bounces back and comes back to where the sound was made. That's what we call an echo.
