Social Welfare Professor Ron Avi Astor, an authority on school violence, spoke to media outlets in the United States and abroad after a mass shooting at a Nashville school that left three 9-year-olds and three adults dead. Astor told the Australian Broadcasting Corporation that the world is exhausted at what feels like a never-ending string of tragedies targeting children. Even as new research shows that day-to-day violence on school campuses has declined, mass shootings are on the rise. “I think what we’re experiencing right now, worldwide, is a contagion,” Astor said. People who tend to be suicidal and obsessed with firearms are “actually trying to break records and create a sense of terror in society and perhaps the world so that their names will be remembered.” Astor also spoke to Reuters, The 19th and Voice of America Eurasia (around minute 48) on topics including the Nashville shooter’s profile and the need to adopt safety measures without creating a militarized environment on campuses.
