the US does seem to have a rather unique problem with school shootings. it's certainly worth investigating why this is the case and considering countermeasures. at the same time, and I know this is a cold thing to say, the issue really gets blown out of proportion for political reasons. it's about as likely for a US student to get killed in a school shooting as it is for you to get hit by a bolt of lightning.

> From outside that society, how people put up with this, living with regular active shooter drills, managing the additional anxiety, etc, is definitely going to be of interest.

I was in grade school not that long ago, and quite frankly, there wasn't much to "put up with". we did active shooter drills as or less frequently than fire drills (not often). I don't remember ever feeling anxiety about being shot at school, and I am a lot more anxious than the average person.
