On Monday, the head of the International Association of Chiefs of Police — one of the largest police organizations in the U.S. — issued an apology for law enforcement’s “historical mistreatment of communities of color.” Robyn McDougle, Ph.D., an expert on police community relations and an associate professor of criminal justice at the L. Douglas Wilder School of Government and Public Affairs, called it a “very important step” toward positive police community relations.
