This isn’t really going to help Bostonians feel safe, now is it? Federal prosecutors said Monday that James “Whitey” Bulger had traveled back to Boston during his 16 years as a fugitive—in disguise and “armed to the teeth.” Bulger, the once infamous head of Boston’s Winter Hill Gang, is accused of 19 murders and various other crimes. He was arrested last week in Los Angeles with his girlfriend, and he apparently waived his Miranda rights. He told prosecutors he traveled to Boston to “take care of some unfinished business,” prosecutors said, but Bulger did not disclose whom he visited. Meanwhile in court on Monday, Bulger’s lawyers argued that the FBI should not be allowed to release any more information about the case, since they fear the accused mobster will not be able to have a fair trial.
