Furthermore, the financial and social investment in prisons means that black and brown youth become, essentially, fodder for the machinery of capitalized incarceration. The steady supply of guns in the U.S. makes an already untenable situation even more dangerous, and all of us must raise our voices, write to Congress, hit the streets in protest, attend budget meetings of local municipalities - all to state our opposition to such criminal procedures and practices for our youth.

Hip hop scholarship must strive to reflect the form it interrogates, offering the same features as the best hip hop: seductive rhythms, throbbing beats, intelligent lyrics, soulful samples, and a sense of joy that is never exhausted in one sitting.

I think we have to face right in the center of the hurricane, if you will, Martin Luther King, Jr.'s foibles and faults.

I went to see Chris Rock on Saturday night here in Atlanta, and he made a statement in his comedy. He said, look, when you're the big person, when you're the rich person, poor people can say stuff about you, but it's downright wrong and brutal for rich people to beat up on poor people.
