Preventing mass shootings through threat assessments and treatment is an unusual tactic for an agency known for its crime fighting and not for interventions. The achievement stands out during a time when President Barack Obama made curbing gun violence a priority for his administration, yet has had very little success.
Mass shootings like the rampages in Newtown, Connecticut, the Washington, D.C., Navy Yard and the Aurora, Colorado, movie theater do not represent the majority of gun violence.
