no profit in dealing with the mentally ill, big profit in selling guns
No less than 80 percent of the perpetrators in these 61 cases obtained their weapons legally. Acute paranoia, delusions, and depression were rampant among them, with at least 35 of the killers committing suicide on or near the scene. (Seven others died in police shootouts they had little hope of surviving, regarded by some experts as "suicide by cop.") And according to additional research we completed recently, at least 38 of them displayed signs of mental health problems prior to the killings. (That data is now included in the interactive map linked above.)"
