In December 1965, three members of the Ku Klux Klan were found guilty over the murder of white civil rights activist, Viola Liuzzo, in one of the first successful prosecutions of its kind in the United States. Viola Liuzzo was killed on the final day of the Selma to Montgomery march, when thousands of civil rights activists marched to demand that blacks be allowed to register to vote. Witness talks to one of the lawyers involved in the landmark case.
