Harry Reid?? Wow that explains a lot.
As for law enforcement being able to penetrate Michael's real controlling interest in the hotels and casinos, I suspect they could not do so in a way would have been admissible in court. The reason I say this is because in his testimony before the committee, Michael said under oath that he had a small interest in the hotels and casinos, and then at Tom's prompting then added that he also had stock in ITT and something else ... as if to show he --- like Roth --- was an "investor." If they could have penetrated his real ownership, his statement that he had a small interest would have itself been perjury --- the very thing for which they were trying to set him up, and they would not have needed Pentangeli. Also, I imagine Questeadt would not go there because such an investigation would have revealed that Hyman Roth had a much bigger hand in things than he would have wanted to be revealed.
