> The numbers don't seem to bear this out. There seems to be a fairly proportional relationship between gun ownership and per capita gun deaths; see point two:
That's highly misleading. The tweet conflates gun ownership with gun counts. The chart largely illustrates the tiny percentage of gun hoarders expanding their collections.
> Rates of personal and household gun ownership appear to have declined over the past decades – roughly two-thirds of Americans today say they live in a gun-free household. By contrast, in the late 1970s, the majority of Americans said they lived in a household with guns.
> But America’s gun super-owners, have amassed huge collections. Just 3% of American adults own a collective 133m firearms – half of America’s total gun stock. These owners have collections that range from eight to 140 guns, the 2015 study found. Their average collection: 17 guns each.
(See also the chart showing a couple percent increase in female gun ownership, but a fairly hefty decrease amongst men.)
True, but it is still false to say that more guns necessarily means more gun crime. I don't think this chart proves anything, it just shows another perspective of the data.
Another point of interest is the number of CCW issued (estimated to be around 17 million now) and the liberalization of carry in general since the 1980s.
I think there is a point in diminishing returns--some gun control measure are more effective than others--but many places in the US have not even plucked the low-hanging fruit.
