> they're not worth worrying about at the individual level

Just as an anecdote: My company tried to recruit an executive from Britain many years ago. He had young children and was concerned about the high rates of child mortality due to firearms and motor-vehicles deaths (the top two causes of death for children in the US) compared to the negligible risk in the UK.

While his underlying concern wasn't specific to "school shootings", he did point out that our blasé acceptance of them was another example of our comparatively higher risk tolerance.
