1,700 people out of ~50 million K-12 students in a 22 year period.
.003352% chance of injury or worse over 22 years. And now I realize the denominator should be bigger because it doesn't count faculty/staff or college students.
There's no reason to live in fear of school shootings. (But there should still be much greater gun control.)
I also think that it's fair to think about other examples of exposure to violence and not just the Parent's example of weekly school shootings. Speaking of gun violence, I'm not sure I know anyone personally in the USA who haven't been impacted by it, whether that's knowing someone who was hurt, having to lock down at work or home, having to drive a different route home because of an active shooting, or just hearing it and then hearing the sirens. Of course, these are not all equal, but it's interesting to think about.
