On May 5 , 1970 , the day after National Guardsmen had shot and killed four students at Kent State University , Keith Green was arrested at the University of Oklahoma for carrying a Viet Cong flag in violation of a state law prohibiting the display of a " red flag or emblem of anarchy or rebellion " . After 12 lawyers had refused to defend the student , Jones took the case and was promptly dismissed from the Enid , Oklahoma law firm where he was employed . Jones argued in court that the disloyalty statute was unconstitutional and the judge dismissed the case , overturning the statute . Later Jones would go on to represent Abbie Hoffman , the radical Yippie , when Oklahoma State University refused to let him speak on campus
