With apologies if this has been posted before pertaining to "Goodfellas."

I don't know why I never thought of this before, but who gave Jimmy Conway permission to start killing all of the Lufthansa crew? I know all of the men weren't "made" guys, but I would think that one or two may have been? And since Jimmy could never be made because of his Irish heritage, how did he get away with whacking guys from Mafia crews? Somehow I can't imagine Paulie giving Jimmy the permission to whack all of those guys...
