Question about Vince (possible spoilers)
As is clearly explained, each of the five casinos had a man 'inside', i.e. one of the 11 who was employed there, and could--among other things--give Tony Bergdorf access to the electrical box.
But what I don't understand is...how could Vince Massler be a porter at the Sands, let alone have insider info, when he was emceeing at the club in Phoenix only a few days before?
