Bulger insists he was not an FBI informant, despite the bureau’s acknowledgment that he was, and he says that a former federal prosecutor, who died in 2009, promised him immunity for all his crimes.
Sunday, who befriended Bulger when both were inmates at the Atlanta federal penitentiary and at the federal prison on Alcatraz in the 1950s and 1960s, said Bulger has yet to be convicted of anything and deserves basic amenities, like watching television, listening to a radio, and getting regular exercise.
In an earlier letter to Sunday, Whitey said, “Wish I was back on Alcatraz.”
