how many mass shootings involve mental illness of shooter?
One study that focused on risk assessment of mental illness and violence found that the stigma attached to such illnesses prevents those who require help from actually seeking it. The study pointed out that since 1983 there have been 78 mass shootings in the U.S., resulting in 547 deaths. The mental health of the shooters was the mediaâs prime focus in each case. Mental status aside, in the past decade alone, gun-related violence accounted for the deaths of over a quarter of a million people.
