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.)
From wikipedia it looks like there's 13,000 school districts in the US - so 1 in 10 (!!!!) has had a school shooting in the last 22 years. Am I doing this right?
But I agree with you that it affects the school and community deeply, even in surrounding communities. I live in Texas, and the whole state was deeply affected after Uvalde. A relative's school got evacuated a few weeks later out of what happened to be a false alarm, with the relative forced to exit the school hands above their head to show they didn't have a gun. They were on the complete other side of the state, probably like a 6 hour drive away.
