'Whitey' Bulger Appeals 2013 Racketeering Conviction On 11 Murders

(Reuters) - Lawyers for former Boston mobster James "Whitey" Bulger on Thursday filed a formal appeal of the sweeping 2013 racketeering conviction on charges of committing or ordering 11 murders in the 1970s and 1980s. The U.S. District Court judge who heard his trial committed a "constitutional error" by refusing Bulger's request to argue that he had been granted immunity for his crimes by corrupt Justice Department officials, the attorneys said in court papers.
