"Road traffic crashes are a leading cause of death in the United States for people ages 1–54"[0]
I wonder if you speeding in your car increased the likely hood of death for someone more than collecting your son from a rumored school shooting. Not saying you were wrong to do that, obviously this is something that comes to the front of your mind when something is wrong at a school. The disconnect between risks we find acceptable, and those we don't is interesting though.
