What led Michael to conclude, very soon after the Tahoe shooting, that Roth was behind it?
FFC told Michael: "If Roth wasn't behind it, then I have to rewrite the whole screenplay."
However, more seriously, who else? Who were Michael's enemies? None that we know of except Roth. No mention of the Commission or any other Dons. However, it is curious that a non-Mafioso like Roth thinks he can murder a Mafioso (and a Don none the least)
without Commission support.
