Active Shooter Safety Resources
An active shooter is an individual actively engaged in killing or attempting to kill people in a populated area, and recent active shooter incidents have underscored the need for a coordinated response by law enforcement and others to save lives. The FBI is committed to working with its partners to protect schools, workplaces, houses of worship, transportation centers, other public gathering sites, and communities.
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.
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.
FBI Jurisdiction in Active Shooter Incidents
Shortly after the tragic shootings at Sandy Hook Elementary School in Newtown, Connecticut in December 2012, the FBI sought ways its personnel could better assist its law enforcement partners. Two actions enhanced these efforts.
First, the Investigative Assistance for Violent Crimes Act of 2012, signed into law by the president in January 2013, permits the U.S. attorney general—at the request of appropriate state or local law enforcement personnel—to provide federal assistance during active shooter incidents and mass killings (defined by the law as three or more people) in public places. The attorney general delegated this responsibility to the FBI.
Second, working with other cabinet agencies, the FBI is finding ways to help prevent and respond to active shooters. A White House working group—consisting of the Department of Justice (DOJ), Department of Homeland Security, Department of Education, and Department of Health and Human Services—is part of a broader initiative, Now is the Time, undertaken after the Sandy Hook shootings. DOJ, led by the FBI, was specifically tasked with training law enforcement and other first responders to ensure that protocols for responding to active shooter situations are consistent across the country.
