Most of the time it's true that the top ten cities have a major black percentage ( my state capitol Jackson is 70-79% black) but all those cities share a similar historic economic decline and drug trade boom. Same situation repeated nearly nationwide. But have notice that almost the same cities had the infamous reputation BEFORE they was majority black ? Not trying to start a ruckus just saying study the history of different cities crime past and look at demography then and you'll see that the cities reputation have already been established. Besides there are too many black majority communities to name that have average to low crime, they're just not newsworthy
