The Federal Bureau of Investigation reports:
Recent active shooting incidents have underscored the need for a coordinated and consistent law enforcement response to these incidents. And two recent actions—the passage of the Investigative Assistance for Violent Crimes Act and an administration initiative targeting violent crime—have enhanced FBI efforts to better assist its law enforcement partners who are almost always the first on the scene. Our new Active Shooter and Mass Casualty Incidents webpage highlights some of these efforts—training we provide to first responders; conferences we hold for law enforcement executives; operational assistance we offer in the event of an active shooter event; and assistance we offer to victims. The webpage also contains links to FBI publications on the topic, active shooter incident statistics, and a link to a public service video created by the city of Houston.
