A Newsweek story on the recent mass shooting at a Georgia high school called on UCLA Luskin’s Ron Avi Astor to share his expertise on campus violence. The suspected gunman, a 14-year-old boy, and his father have been charged in the shooting, which killed two teachers and two students and injured nine others. While the motive behind the George incident remains unclear, Astor described some common traits shared among school shooters. Many are suicidal, “but suicidal thoughts are fleeting,” said Astor, a professor of social welfare and education. He added that many shooters seek to sow terror on a national level. “It’s not necessarily always to target one person, or just somebody with mental health issues,” he said. “The goal is to commit terror for every child and parent in the United States, and they use the media to do that.”
