Those poor kids at Santa fe only wanted books Instead they got magazines
Is this meant to be a joke about a school shooting?
Of course, it's really sad but there's nothing you can do about it.
Jokes about school shootings are insensitive and not something you should tell. When mass shootings are joked about, it normalizes them and makes people take them less seriously. That in turn can convince the next mass shooter that shootings are normal and accepted since people are willing to laugh about them.
