Why is it so hard to hire black police officers?

How do you better diversify a police force? That's the question countless departments around the US are facing as pressure to hire more minority officers mounts - particularly after last year's events in Ferguson, Missouri.

One of those departments is in Norfolk, Virginia, where 16% of officers are black in a city that is 43% black.

Chief Michael Goldsmith says his department has redoubled its efforts to diversify, including trying out new tactics and boosting funding.

But some in Norfolk's African-American community say relations with the police department are too tense for a dialogue about recruitment.
