I think only concentrating on those that were shot or injured ignores the impact of being exposed to gun violence, especially during formative years in a situation where it's in the building you're in and results in the death or injury of your friends. Hundreds of thousands of people in the USA have experienced being in a school shooting event.

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.
