It's still going as I type this up. Turnbull is just now being asked the question I would have asked, the Australian response to the 1996 mass shooting, which was to coordinate a reduction in the firearms count in the private sector. Turnbull seems to have responded forthrightly but has emphasized that the 'context' of Australian life versus the United States is profoundly different. Good answer, from his point of view.
Trump is full of his usual blandishments, making most things self-referential.
