Perpetrators Interpretation

Behind the stark statistics, a chilling profile emerges: the typical school shooter is often a deeply troubled adolescent male—a current or former student who obtained a gun from home, exhibited clear warning signs of crisis, and planned his attack for over a year, revealing a systemic failure to intervene in a cycle of trauma, alienation, and accessible firearms.
