A recent study has found that there's no evidence school resource officers make school safer.The Justice Policy Institute, a Washington-based non-profit, conducted the research. Marc Schindler, who heads the organization, said there are proven ways for educators to make schools more safer by hiring more counselors and psychologists instead of adding more law enforcement officers.However, a former school resource officer, Marc Ridgell, said law enforcement is the best way to make schools safer.Ridgell spent eight years keeping students safe at Grimsley High School in Greensboro.Researchers at the Justice Policy Institute said SROs come with unintended consequences.The spokesman said having officers in school lead to more suspensions, expulsions and legal actions, especially among students of color.
