...Rocco would be an obvious choice to be involved in the plot, far more obvious than Fredo. He was the one in charge of security at Lake Tahoe. If I were Hyman Roth, I would definitely consider him to be part of the plot. His role would be crucial for the plot to succeed. He would have been far more important than Fredo.
I'm not saying I'm totally convinced that this is the case. It's just a theory I have. And frankly, it's not that unplausible.
Not implausible at all. As Michael said, nobody other than Tom was above suspicion.
However...having seen and taken part in what happened to Paulie as a result of selling out HIS Don, one would think that Rocco of all people would be a bit smarter than to take such a risk.
