I have no doubt that Australia has fewer mass shootings than the US by pretty much any reasonable metric, but we should be careful in our comparisons. First of all, definitions vary widely on what constitutes a “mass shooting”, so we should always give our definition and make sure we’re applying the same definition to both operands (notably, by most common definitions, Australia has had several mass shootings and quite a few more mass murders since 1996). We should also adjust for known dependent variables, like population, population density, crime rates, number of guns in circulation (i.e., we would intuitively expect fewer mass shootings from a small, sparse, low-abiding country with few guns in circulation irrespective of gun laws)—Australia has only 8% of the US population and only 10% of the density—not sure about crime rates. I also suspect there were fewer guns in circulation prior to 1996, so even if officials could get the same share removed from the US market, it would likely leave more guns in circulation than in America (even adjusting for population, etc)—I also doubt Americans would be as willing to give up their guns as Australians were in ‘96, so the odds that America could get the same share of guns off the market as Australia did seems unlikely. That said, I’ve read that Australia’s gun count has crept back up to pre-96 levels (not sure if that is per capita or not), which is interesting—potentially it suggests there’s something else going on: either it matters what type of guns are banned (e.g., semi-automatic handguns), or perhaps there’s an altogether different reason or hidden factor behind the decline in Australian mass shootings. In any case, mass shootings is probably the wrong metric, but rather we probably want to look at number of mass murder deaths overall (presumably some people switch to stabbings or arson, but both of these are probably result in fewer fatalities). It’s also not clear to me why we fixate on mass murders/shootings rather than homicides overall—is it really worse when 10 people are killed all at once rather than 10000 people killed individually? |
The UK for example changed gun laws after a mass school shooting 26 years ago. Not a single one since.
