A 37-year-old Dublin man has appealed against his conviction for being the murderer in drag, who gunned a man down with a sub-machine gun in a busy car park.

Christopher McDonald’s lawyer has argued that the jury should not have heard his reply to arrest: "Go F**k yourself", as it indicated a hardness that would be expected from a professional hitman.
