It looks like Whitey's ticket was punched before he ever arrived at Hazelton.
"Numerous inmates at Hazelton knew in advance about Bulger’s impending arrival, and even placed bets on how long he would stay alive, because prison officials had been cavalier in how they shared information about his transfer.
— Despite the target on his back as a federal cooperator, he was placed in a unit with at least one rival mobster from Massachusetts.
“In our view, no BOP inmate’s transfer, whether they are a notorious offender or a non-violent offender, should be handled like Bulger’s transfer was in this instance,” the inspector general report said, referring to the Federal Bureau of Prisons."
