In the last 53 years, there have been 2,057 shooting fatalities in K-12 schools in the US [0]. That's an average of 38 per year. As of 2020, there were 56,282,248 K-12 enrolled students [1]. So there's a .000067% chance that any given one of those students will be shot and killed in any given year.

That's what you're worried about? A .000067% chance? You must live a life of crippling fear then, the number of things more deadly to your kids than .000067% is staggering. I assume you never let them enter a vehicle of any kind, for example.

By the way, of that 38 per year number, less than 10% happens inside a classroom [0]. The most likely location is outside in the school parking lot, a violent dispute between students, and not a "mass shooting" scenario. So if you were mostly concerned about "mass shootings", the odds of death are over 10 times less than .000067%.
