Mass Violence Threats: The Actions that Speak Louder than Words

Mass violence actors and school shooters often engage in research and planning before committing an attack. Law enforcement may be tipped off to something said or done, but how do we get beyond what is being said? How can law enforcement identify what the threat actor really cares about and doesn't want anyone to know? In June 2022, San Diego initiated the Rapid Search by Keyword Lookup (RSKL) Program, an investigative process to leverage threat actors' Internet consumption to gain critical insights into their motivation, research, interests, operational planning, and firearms procurement to effectively support the evaluation and mitigation of mass violence threats.
