I watched an american gang film set in compton a long time back, i cant remember its name?

i think it was a low budget movie, the main actor lives a simple life, but something big happens and he comes back as a gangster lord. somebody commited a crime and blamed him or set him up. it is revealed he comes from a long line of gangsters and the people in the hood all have a great respect for him and his family. he is the last of his lineage. he goes into the prison where the guy who set him up is incarcerated and feeds him to sharks...

can anybody tell me the name of the movie?? if i'm not mistaken, terrence howard pays the role of a drug dealer(supporting role) but i'm not too sure about this
