school shootings in 2024 average 1.8 per every school day (0.9 at 365 calendar days a year). The next highest country - Mexico - has one every 24 school days (one every 46 calendar days)

I would not call that a deterrent.

Edit: oh God, it's actually even worse. I assumed I was looking at yearly stats for Mexico. it was actually a decade. It's one every 15 months
