Sorry, I took the total gun count(~400M) and didn't state that I did some math based on how many adults there are in the US since children and the extremely elderly tend to own far fewer guns than run of the mill adults.
The result is still more or less the same if there is 1.1 guns per capita.
that's not unreasonable. I saw your post a few minutes after another that claimed there were a billion guns in the US, so I was starting to wonder if this was a common misconception.
I personally don't feel that pervasive civilian gun ownership is incompatible with proportionate policing, but that's certainly a debate that reasonable people can have.
per capita in run of the mill statistics is just a raw division of things over population (people or other organism in question). per capita income isn't dividing total income over "employed earners" for example.
The result is still more or less the same if there is 1.1 guns per capita.
