Green was involved in extradition proceedings in Los Angeles in 1949. Green's case originated in March 1946, when he and his cousin went to a liquor store in St. Francisville, Louisiana, and got into an argument with the store's owner. The owner thought Green was threatening him with a gun, so he took out his own gun, and Green fled the store to avoid being shot. Fearing mob violence, Green moved to Los Angeles, got a job and joined the Mine, Mill and Smelter Workers union. On Thanksgiving Day 1948, Green was robbed at gun point while walking on a Los Angeles street. He reported his loss to police, who later arrested him because he was wanted in Louisiana for his former robbery offense. Green was taken to the Los Angeles County jail, where he claimed policemen handled him violently, aggravating an old injury and forcing him into a wheelchair. The Civil Rights Congress, with support from the Mine, Mill and Smelter Workers union, defended Green, calling upon California Gov. Earl Warren to prevent Green's extradition to Louisiana. A Los Angeles judge dismissed the case on March 11, 1949, allowing Green to avoid extradition.
