A heavily armed young man is accused of killing 17 people after opening fire on terrified students and teachers at Marjory Stoneman Douglas High School in Parkland, Fla., on Wednesday. It was the third mass shooting in the past four months in the United States.
Nikolas Cruz, who has been linked to a history of mental illness, is believed to have used a legally obtained AR-15 in the shooting. The attack has led to widespread conversations about links between gun violence and mental illness, and how lawmakers and interest groups are debating potential policy responses.
“Two things typically happen in the wake of a mass shooting. First, politicians claim that mental illness is the major cause of violence in America. Then, advocates for people with mental illness respond by denying there is any relationship whatsoever between mental illness and violence. Both groups are wrong. Research shows that the association between mental illness and violence is not strong, but it does exist.”
