This case appears to present much more egregious enabling/failure to act by the parents — resulting in the criminal charges brought today.
Typically, school shooters are troubled, lonely, dysfunctional kids, — who have passive parents or parent, — who have surrendered to shame or fatigue or conditioning, whereby they ignore/suppress obvious red flags. They make excuses for their kid’s odd or worrisome behavior, and assume “things will turn out for the best” over time.
Communities and schools need to be more proactive. Constructive interventions.
