Huron's is correct. Tony Spilotro was under Joey Lombardo, and Lombardo was responsible for Vegas for the Outfit during this time period.

If we are going to look back, and analyze the decisions and what happened....in my opinion, Spilotro was a good choice for the "outside man" Vegas role for the Outfit. He had the violent resume, had followed orders and had successfully run a profitable book. It was time for him to leave Chicago because he had become a suspect in several murders, and had the contentious relationship with Chicago law enforcement, especially Roemer. Lefty was a good choice for the "inside man" role because of his excellence at setting betting lines and his administrative skills.

Lombardo should have reigned in Spilotro, especially when it was obvious that LVPD was watching him. As far as I can tell from what I have read, Lombardo did not try to get Spilotro under control, so it seems either (1) Lombardo was complicit, or (2) Lombardo did not know all the shit Spilotro was pulling. I lean toward #1. We know that Lombardo was greedy, and it is possible he was getting a cut from the Ant. I also understand that Lombardo was a "hands on" style manager, and I find it hard to believe that he did not have a good idea of what was happening. I believe that Lefty made it clear to Lombardo that he objected to some of Spiotro's activities.

At the same time, the FBI and LVPD were investigating how the skim money got back to Chicago. Lombardo knew that the money and bag men were being surveilled. Instead of changing things up, or cooling it off, he toyed with the Feds and LVPD when he had 2 bagmen from KC get pulled over with donuts in skim bags.

So, I would place the responsibility for the Outfit's loss of Vegas casinos and skim on Lombardo.

Regarding Auippa, I understand he had a horrible temper. When issues arose, Auippa would blow up, yell at people and then fume. After a while, he would cool off and start reasoning.
