My colleague Uri Friedman wrote about the impact of the Port Arthur massacre in the wake of the shooting in San Bernardino, California in 2015. He noted that, among other things, the Australian government banned automatic and semiautomatic firearms, adopted new licensing requirements, established a national firearms registry, and instituted a 28-day waiting period for gun purchases. It also bought and destroyed more than 600,000 civilian-owned firearms, in a scheme that cost half a billion dollars and was funded by raising taxes. The entire overhaul, Friedman pointed out, took just months to implement. [snip]
Last year, on the 20th anniversary of the Port Arthur massacre, John Howard, the center-right leader whose government introduced and passed the legislation, said: It is incontestable that gun-related homicides have fallen quite significantly in Australia, incontestable. In the interview, he also cited a 74 percent decline in gun-involved suicide rates as evidence of the legislation working. But as the Australian Broadcasting Corporation pointed out: While it is accurate for Mr Howard to assert that gun-related homicides and suicides have dropped since his reforms were implemented, there is more to it. Studies on the impacts of his reforms have come to varied conclusions and experts contacted by Fact Check said other factors would have influenced the drops, even though the reforms are likely to form part of the story. The ABC report said social support or government investment in social welfare are common factors that help depress crime rates and could be linked to the drop in firearm homicides and suicides.
