This. The crisis actor is who you put on TV to frame the narrative. The parent no one has seen before, the kid who was in some class that no one's kid was in. Not everyone is, most are actual students, sharing their stories of the maladjusted kid who killed himself at the end of the spree... no they never saw him but let me tell you about how scared I was hearing the shots while hiding behind my desk. The crisis actor gets the sound bite in.
