Your right on point about black authors and its going to be a small number of them due to that segment of the black community being elderly per say. Also, Drugs trafficking have been the lucrative racket since the 70s and more are interested in the Drug Kingpins then Policy Kingpins. Have you read Sean Penn " Black Brothers Inc" ? I use to own it that book but it got lost. It's about the Black Mafia in Philadelphia and he spoken about the ridicule from his academic peers ranging from " Black mafia? Do you mean the Muslim Mob?" to " Blacks don't have organized crime , they have gangs". Funny that last one is the most common view I read on other sites & this forum too.
