Not that surprising, if you think about it. The geezer is from Australia, and Australia used to have this problem of mass killings until the government did something about it:
Australia’s 1996 gun law reforms were followed by more than a decade free of fatal mass shootings, and accelerated declines in firearm deaths, particularly suicides. Total homicide rates followed the same pattern. Removing large numbers of rapid-firing firearms from civilians may be an effective way of reducing mass shootings, firearm homicides and firearm suicides.

As for the NRA? Not peep/tweet from them since all hell broke loose.
