A VCU poll found more than 80 percent of residents believe mental health services are crucial to keeping schools safe. But mental health centers and services at colleges, universities and K-12 schools are chronically underfunded, said Dewey Cornell, a University of Virginia education professor. “We are not doing enough to identify and assist individuals who have serious mental health and educational support needs, including those who are at risk for violence,” he said in an email, stressing that school shootings are rare.
