^^^thats more or less a recollection of what you saw in the 'Casino' film.

Tony Accardo didn't send anyone out to run Vegas. Joey Lombardo was given the control over Las Vegas rackets & sent one of his top men, Tony Spilotro, out there to run things for him.

Michael Spilotro was not a tough guy nor was he respected on the street. He was a lackey to his brothers Tony & Victor, who were real Grand Avenue hard heads. Michael was a cokehead pretty boy who's desire was to use his mob connections to become a Hollywood actor (lol).

Regarding the Vegas situation, Lombardo knew exactly what was going on, obviously. They were his rackets, after all. He was out there a great deal during the 70s & early 80s. I maintain that Aiuppa & Cerone wanted him dead as well.
