(when " listing any homicide that occurred within the vicinity of a school")

It isn't reasonable, and that is exactly why non shooting homicides are included in lists of all homicides but not included in lists of shooting homicides.

Yeah but there the issue of deception by lack of context. Wiki, so far as I can tell, has no comparable page or even information on general homicide at schools, only the gun stuff. Imagine, if somebody started listing all fatal taxi/rideshare incidents with a female driver. There would be a lot incidents, but it'd be completely misleading without the context of how that compares to incidents of all drivers, and so it would serve little purpose other than to implicitly misinform people.

So in the case of schools when there are 130k+ educational institutions in the US basically every single thing that you can imagine happens, and happens a lot. But it says absolutely nothing about the relative frequency of that event, but much more so about the fact that there are a massive amount of schools.
