Biography
The Clowns riot started after a Arthur shot and killed three rich, business men that were assaulting him because of his uncontrollable laughter. This caused an uproar because everyone saw it as the people fighting against the rich, causing outrage against Thomas Wayne. They also attacked two detectives after fighting amongst them took place before one of the detectives shot and killed a clown, causing him to be brutally assaulted by the crowd of clowns because of what they did. They then began rioting around Gotham City after the live murder of Murray Franklin and managed to save Arthur from the authorities and hailing him as their leader. Although we don't get an explanation of what happened to the riots afterward, it's presumed the Gotham police managed to fight off and stop the riots before taking Arthur to custody, ending the Clowns organization.
