Biography
James Black was detained in Mississippi in the context of the civil-rights movement, as documented in Charles Payne’s interview-based history.
Payne identifies Black as the driver among five SNCC workers jailed and beaten in Columbus, Mississippi, in early June 1964. It says Black was charged with reckless driving and running a stop sign, fined $28, and the group was released the next day. No conviction, precise admission, discharge or numerical duration is inferred.
