ROCHESTER, Minn. –The Rochester School Board may choose not to renew its contract with the Rochester Police Department for on-site officers. There has been ongoig uneasiness about uniformed “school resource officers” on school grounds and hallways. The Board now has ordered a study on the cost of alternatives to SROs, perhaps putting trained educators in the positions. Likely an alternative would cost more. The district and the Rochester Police Department now share the SRO salaries.
