BPD Appoints Highest-Ranking Black Officer In Its History

Boston Mayor Marty Walsh has made a flurry of appointments this week, and one of them broke a race barrier of sorts: he and his new police commissioner, William Evans, named an African-American Boston police superintendent to the number two post in the force. That makes William Gross the highest-ranking black officer ever in the city's police department.

WBUR's Sacha Pfeiffer discusses the historic appointment.
