Ray Hill, Houston icon and civil rights activist, dies at age 78
Hill was very active in Houston politics for a long time. I remember this case

Upon shouting at police in an attempt to divert their attention from his friend during a confrontation, appellee was arrested for "wilfully . . . interrupt[ing] a city policeman . . . by verbal challenge during an investigation" in violation of a municipal ordinance making it unlawful for any person "to assault, strike or in any manner oppose, molest, abuse or interrupt any policeman in the execution of his duty." After his acquittal in Municipal Court, appellee brought suit in Federal District Court challenging the ordinance's constitutionality and seeking, inter alia, damages and attorney's fees. The District Court held that the ordinance was not unconstitutionally vague or overbroad on its face, but the Court of Appeals reversed, finding that the ordinance was substantially overbroad since its literal wording punished and might deter a significant range of protected speech.
