This photograph of a Harvard University Police officer at a Boston protest against mistreatment of people of color at the hands of police was widely shared on Twitter. The officer in the photograph, and six others dispatched in response to a request for mutual aid from the Boston police department, were members of the HUPD bicycle patrol, an innovation Riley instituted in the 1990s to improve community relations.
