I can imagine many members of the general public up in arms shouting "how could they" and other similar phrases.
The results seem reasonable though. In a seminar I would be tempted to ask for the "policy implications" of these results. Given the relatively infrequent number of school shootings, knowing the impact on exam results may not be considered of the utmost importance.
Why would young men be affected more than young women?

In this paper, we study how high school students reacted to the shocking news of a school shooting. The shooting coincided with national high-school matriculation exams. As there were exams both before and after the shooting, we can use a difference-in-differences analysis to uncover how the school shooting affected the test scores compared to previous years. We find that the average performance of young men declined due to the school shooting, whereas we do not observe a similar pattern for women.
