Kennedy got his break when he was discovered by James Cagney. His first role was of Cagney's younger brother in City for Conquest in 1940. He portrayed good guys and bad guys equally, appearing in Western films and police dramas.
Kennedy was a professional, a government official carrying out his instruction to the letter of the law.
Kennedy's reports that Kilrush's plight was highlighted; most notably by Poulett Scrope M.P., his pleadings lead to the investigation of the Union in May 1850.
ArthurKennedy had made powerful enemies, (Vandeleur and the guardian of the Poor Law), and it would be safe to say that they may have had a hand in Kennedy's transfer from Kilrush to Kilkenny shortly after he returned from giving evidence at the Parliamentary Inquiry in London.
