Firstly, the framing of mass shootings in media outlets has given them notoriety which means giving the perpetrators name out directly fuels more shootings. Secondly, schools do not have proper protections in place. Thirdly, a huge number of these perpetrators were already under surveillance by the government.
If you’ve spent really any time at all thinking about these issues then you should be aware of some very obvious differences between driving deaths, even at the hands of people using cars as weapons, and shooting deaths. The key is in the benefit (need for product) versus harm of each, as well as their designed use cases.
The nra isn’t paying people to shoot up schools, they’re paying lawmakers to prevent the cdc from conducting studies on gun violence and paying those same lawmakers to make it easier to buy and carry guns everywhere. The very steep increase in gun ownership / shooting deaths over the last couple decades is the result of this
Now you could point to LA, AR, MS, and NM in comparison to MA which would be a good example of your point. I would however point to ID, MT, WY, and WV in comparison to OH which would be a good example against it. Suffice it to say, it's likely not the biggest determining factor in shooting deaths if we can see such discrepancies already while only taking into account states with high ownership rates compared to a single low ownership rate state.
After that you might say "that is unfair, compare us to another country", in response I would point to a number of other countries that already have high firearm ownership rates and low gun crime, or other countries that already have low ownership rates and high gun crime. Studies about crime and violence aside, the 2A does not say "shall be infringed if criminals commit crimes". Thats a policing matter, not a matter of our rights.
