Louisville police found John W. Riddle riding in a car with a "known prostitute." In his pockets, they allegedly found a bottle of Viagra. The prostitute allegedly told police he had picked her up to have sex, and Riddle was charged with prostitution. Riddle is the chairman of a local anti-pornography group and has led efforts to keep adult bookstores and sex shops from opening in residential neighborhoods. He has since resigned that position.
