It’s extremely unlikely a given kid will be present at all during any kind of shooting at school, the vast majority of which aren’t indiscriminate killings and which may not involve students or staff at all (a shooting that just happens to take place with at least one involved party standing on school property)—over all 13 years of k-12 school. I ran the numbers and it was firmly in “not even worth a thought” territory. I cast the net of the definition of “school shooting” as wide as remotely reasonable, and made the criterion present at the building for, not hurt or killed, and it was still not worth worrying about. The odds are even better in the kinds of schools HNers are likely to send their kids to, since a ton of those shootings are drug- and/or gang-related.
