Australia and the USA are vastly different cases, because we begin with well over five times the guns per capita Australia had, and their buyback only collected between 20% and 40% of their guns. To get our guns per capita ratio down to Australia’s current levels it would mean buying back 90% of our guns. Somehow. Math:
If we presume the multivariate relationship between gun ownership and gun homicide from the research is correct, we would have to buy back 80 million dollars worth of guns for every one life saved. Math:
And it’s already been determined by solid research that gun ownership rate has zero (literally zero) impact on homicide rate, even at a multivariate level, when looking at non-domestic homicides. The only type of homicide it impacts is domestic homicide, which amounts to about 2000 per year out of over 300 million people. Math:
