Most of the work Crump does is never heard about because white folks didn't tell you. Crump is from my hometown. I know his family very well. He's not a con artist or an ambulance chaser. People reach out to him. Not the other way around.

I really wish you cats would go down to your local library and look at the old microfiche of old newspapers from the Civil Rights, Nadir of Race Relations (1920s), birth of Segregation Laws and Reconstruction eras. They shyt they're saying about the Ben Crumps, and anyone else that works for black folks, is the same shyt they said about black folks back then damn near verbatim. You even had black folks making the same complaints about other black people you hear today back then.
