The fact that you had to find an article from three decades ago for an instance of killing with a keyboard is telling. All the others aren’t exactly that recent and are mostly isolated cases. Meanwhile, on gun related deaths, there are entire Wikipedia pages for it:

https://en.wikipedia.org/wiki/Lists_of_mass_shootings_in_the...

There are more mass shootings in the US per year than there are days in a year. It’s so bad they need pages for each individual year.

Meanwhile, pages of deaths perpetrated with household items are curiosities. You parent comment stands: tools are designed for specific purposes and are used for those purposes.
