The Rate that Schizophrenics Commit Mass Public Shootings

Sep 4, 2025 | Mass Public Shootings, mental health

According to court opinions, competency rulings, law-enforcement releases, or mainstream reporting that cites those records, seven U.S. mass public shooters since 1998 had a documented diagnosis of schizophrenia — 0.26 cases per year. There was one other case where the family says that the murderer was a schizophrenic. More than 3.5 million Americans live with the disorder, yet only one schizophrenic has committed a mass attack since 2019. That makes the odds of such a crime less than one in 3.5 million—extremely rare. Our detailed information on mass public shooters is available here.

So is there really a question of whether Trump reduced crime in DC? Did the Washington Post inaccurately report murder data to make the drop look smaller than it actually is?
