Biography
Cleveland Brooks was a San Francisco Panther prosecuted on explosives and firearms allegations in 1969. The Party organized a defense campaign disputing the prosecution.
Don Cox’s first-person account describes the April 23, 1969 San Francisco Panther office raid, arrests and tear gas. Cox reports that most of the thirty-six people arrested were released without charges within thirty minutes; Brooks, the officer of the day, remained longer on an assault allegation and was later released without charge. The account does not support converting every individual’s detention to the same exact duration. The Black Panther, May4,1969 vol2 no2, original PDF page 5.
