Boston's soon-to-be top cop William Gross just made history as the first African-American police commissioner in the city. Outgoing commissioner Bill Evans called Gross an obvious choice, saying, "I think we're the best department in the nation, and it's not like we need a change agent to come in and move anything — we just gotta keep continuing what we're doing and Chief Gross is going to do that." But some think that a change agent is exactly what is needed for a city coping with a difficult past on race relations. In an era of heightened police scrutiny, how much of a difference does the man at the top really make?

Jim Braude was joined by Tanisha Sullivan, president of the NAACP’s Boston branch, and Jamarhl Crawford, a community activist and editor of Blackstonian, to discuss.
