many(most) of the school shootings don't fit the narrative.
such as the one lately where the coach tackled the shooter and no one was killed.

and more often than not it is just a gang related shooting that takes place on or near a school. And of course they count it when a cop's gun goes off into the floor in a school, oh the humanity! Some random dude committing suicide in a school parking lot overnight, that's a school shooting.
