Could the US learn from Australia's gun-control laws?

Though gun-related deaths did not suddenly end in Australia, gun-related homicides dropped 59 percent between 1995 and 2006, with no corresponding increase in non-firearm-related homicides. Suicides by gun plummeted by 65 percent, and robberies at gunpoint also dropped significantly. Many said there was a close correlation between the sharp declines and the buyback program.

A paper for the American Law and Economics Review by Andrew Leigh of the Australian National University and Christine Neill of the Wilfrid Laurier University reports that the buyback led to a drop in the firearm suicide rates of almost 80 percent, "with no significant effect on non-firearm death rates. The effect on firearm homicides is of similar magnitude but is less precise.”

Perhaps the most convincing statistic for many, though, is that in the decade before the Port Arthur massacre, there were 11 mass shootings in the country. Since the new law, there hasn’t been one shooting spree.
