The study of North Carolina middle schools found no relationship between increased funding for school resource officers and reduction in cases of reported school crimes. Kenneth Alonzo Anderson, the report’s author and an associate professor at Howard University, said legislators across the country should consider the findings before rushing to put more police officers in schools following mass acts of violence such as the school shooting incident in Parkland. Fla.

“I’m not recommending that we remove police officers from schools,” Anderson said in an interview. “However we need to evaluate what we do and change our philosophy on policing in schools.”
