Dick Gregory's View From the Back of the Bus has become altered to the view from the front of the pulpit as he has attained a position of substantial leadership in the Civil Rights cause. A spokesman who tells it like it is, he is militantly non-violent, calling for patience and justice, Justice, however is the keynote in his appeals rather than law and order as he discusses the disparity between rights for white and rights for black. And why police brutality? Gregory has answers, for both sides, which call for a black man's understanding of the cops and for the cops to understand the problems of the ghetto. He is not afraid to take on any taboo, including the Negro mainstay, the church, which he labels a ""sick comedy"" with its hypocrisy. Or the difference between North and South: ""in the South the white man has misused Negroes physically, but in the North he has misused us mentally""; chestnuts of the revolution but emphasized here with a new ring. There is a practicality in his preachments which make this an honest and a firm book that both Negro and white can relate to. And in view of his prominence as a comedian and as veteran front-liner (even shot once in the Watts riots) this should find a large audience.
