Roy Belton was a Jewish youth accused of murdering a taxi driver in Tulsa, Oklahama in the summer of 1920. He was lynched while Tulsa police directed traffic around the White mob. Being aware of the earlier failure of Tulsa police to defend Belton against a lynch mob, some in the black community offered to help the sheriff's deputies defend Dick Rowland, a black prisoner, in actions leading up to the Tulsa Race Riot of 1921.
