In the relatively small amount of research on this subject that is not influenced by commercial interests, the numbers suggest that defensive gun use is very rare: https://www.sciencedirect.com/science/article/abs/pii/S00917...
Of course there are cases of defensive gun use. But there are also cases of idiotic gun use:
> Deputies with the Escambia County Sheriff’s Office arrested three people after one man was shot. Investigators said the shooting victim was shot after an argument about the victim’s alleged littering.

> A Utah father was taken into custody after police said he told his 4-year-old child to fire at officers following a dispute over an order at the McDonald's drive-thru in Midvale.

Right across the US border Canada manages to have a safe society without everyone packing heat. And it's not like gun ownership is unheard of in Canada, given it's 7th in per capita ownership:

For tracking mass shootings, the US has a separate Wikipedia page for each calendar year:

Meanwhile the list of massacres (not even all being shootings) fits on one page for Canada:

The idea that firearms make one safer, either at home:

or in public:

does not seem to be borne out by the statistical data.
My point is, become familiar with the frequency that these reports happen before you make the claim that it's rare.
