Lone Offender

The current report provides an overview of the data, exploring the various topics encompassed within the coding protocol, including bystander observations, offenders' backgrounds, family and social networks, behavioral characteristics, radicalization, and attack planning. Predicting lone offender terrorism incidents is not possible, but prior research and operational experience support the conclusion that acts of targeted violence, including lone offender terrorist attacks, may be preventable through early recognition and reporting of concerning behavior. The report aims to inform broader goals of enhancing bystander education and awareness, as well to aid the prevention efforts of law enforcement and multi-disciplinary threat assessment teams working to counter targeted violence threats every day. To work toward this objective, the authors examine relevant contextual factors and analyze the statements and behaviors offenders exhibited before carrying out their attacks.
