RT Article T1 Mass Shootings and Routine Activities Theory: The Impact of Motivation, Target Suitability, and Capable Guardianship on Fatalities and Injuries JF Victims & offenders VO 16 IS 4 SP 565 OP 586 A1 Silva, Jason R. A1 Greene-Colozzi, Emily Ann A2 Greene-Colozzi, Emily Ann LA English YR 2021 UL https://krimdok.uni-tuebingen.de/Record/1755889429 AB This study uses the routine activities framework to identify motivation, target, and guardian characteristics influencing the severity of mass shooting fatalities and injuries. Significant findings indicate media-driven motivations, particularly fame-seeking perpetrators, produced more casualties. Open-spaces and schools provided more suitable targets, with open-spaces incurring more fatalities and schools incurring more injuries. Guardianship variables indicated perpetrators with a history of mental illness, as well as incidents involving rifles, more than one gun, and ending in the perpetrator’s death, all resulted in higher rates of victimization. A discussion of findings highlights targeted policy and security strategies aimed at reducing the victim-counts attributed to mass shooting attacks.
