What do you think will happen to Whitey Bulger?

I think that someone might take a shot at him. I mean he's old and crazy. He has no problem going into a courthouse and flapping his lips and ratting out a lot of people. Especially the ex-FBI agents who helped him back in the 90's. He's pissed a lot of people off including the Patriarca Family. Do any of you think someone might try to kill him just to make sure he doesn't talk?
