Although local and state law enforcement agencies are virtually always the first ones on the scene, the FBI has played a large role in supporting the response to every major incident in recent years and has much to offer in terms of capacity, expertise, specialized capabilities, training, and resources before and after an incident occurs. The successful prevention of these active shooter incidents lies with a wide range of public and private entities all working together.

The FBI is committed to working with its partners to protect schools, workplaces, houses of worship, transportation centers, other public gathering sites, and communities.

To that end, the FBI provides operational, behaviorally-based threat assessment and threat management services to help detect and prevent acts of targeted violence, helping academic, mental health, business, community, law enforcement, and government entities recognize and disrupt potential active shooters who may be on a trajectory toward violence. The Bureau also continues its research to identify indicators that could signal potential violent intent.
