Map of 29 mass shootings in 2017 examined by secret service

Secret Service Report: 64% of Mass Attackers Mentally ill

Secret Service National Threat Assessment Center (NTAC) released a comprehensive study on 29 mass shooting attacks in public spaces in 2017 that found

Nearly two-thirds of the attackers (64%) experienced mental health symptoms prior to their attacks. The most common symptoms observed were related to psychosis (e.g., paranoia, hallucinations, or delusions) and suicidal thoughts . Further, 25% of attackers had been hospitalized for treatment or prescribed psychiatric medications prior to their attacks.

This study focused on 28 incidents in 2017, in which three or more persons were harmed and were carried out in public places within the United States. This seems to confirm the findings of Mother Jones which has been maintaining a database of mass shootings and found the mentally ill were disproportionately represented among the perpetrators. It is time for those in the mental health industry to recognize that leaving the seriously mentally ill untreated does cause a spike in violence, rather than denying that violence is associated with mental illness.
