How is HVE defined?


Homegrown Violent Extremism (HVE) describes the preparation or execution of a terrorist act within the context of ideologically motivated violence or plots, perpetrated within the United States or abroad by American citizens, residents or visitors, who have embraced their legitimizing ideology while largely residing within the United States.

How is PSO defined?


Public Safety Officer (PSO) is defined as an individual serving a public agency in an official capacity, with or without compensation, as a law enforcement officer, as a firefighter, as a chaplain, or as a member of a rescue squad or ambulance crew (U.S. Code § 3796b).

Index Attributes


For each recorded incident, the SCI 2000 PSO Index notes eight attributes: (1) date of incident; (2) location of incident; (3) subject (suspect): name, DOB, POB; (4) HVE orientation (racial, religious, or issue oriented); (5) description of incident; (6) weapon(s) used; (7) disposition (outcome of incident); and (8) sources


Validation Methodology: Open source public information captured from at least two unbiased, reputable, confirmed media outlets reporting each incident identified in the SCI 2000 Public Safety Officers Index. The index will also include extremist individuals who had “contact” with public safety officers but their actions were lacking violence or failed to meet the threshold for an ideologically motivated incident.
