There have been 5 school shootings in 2025 across 131,000 schools (k-12) in the US. I haven't bothered to check how Wikipedia is cooking the books, but rough math suggests a 1% chance of being present at a school when a school shooting occurs once per 200 years of schooling.
Certainly not what Google says. Who cares how many schools tbh.
If anything I'd suggest your take shows just how normalized it really is.
