Issues after watching it 10+ times
I read somewhere that unlike he previous two movies we know every scam and trick they're running. This really isn't true because we don't know from the get-go that the FBI agent is Linus's father or that the guys know Toulor is watching them.
One thing I had wondered about was Rusty's line toward the end: "Do you think Nagel was...nah." A deleted scene with Nagel and Livingston has Nagel suggested that the faux earthquake might cause a real one, which it did. He also mentions not knowing how Livingston is going to rig all the machines, which Nagel figured out how to do, on the fly in the casino. This sets up Linus getting "arrested" by Bobby so Nagel can bring in pre-rigged machines.
I don't fully understand that part beginning with Danny saying "the bureau's in the house" and telling everyone to signal Livingston if they get close. Danny knows Bobby, presumably knows his cover is as an FBI agent, and thus "the bureau" could be his reference to Bobby, but why seemingly worry about Livingston getting busted? Why did Frank signal to him? Maybe Livingston wasn't wired to hear everyone? I thought I heard him on the comms after he got "busted". He doesn't actually get arrested but ends up cuffed in a car and thus able to do the hack. Seems to me that Bobby could have done the same with him as he later does with Linus. Walk him out in breakaway cuffs to do whatever else he needs to do. It wasn't a show for Benedict because he later sees/hears Bobby colluding with them. The only thing they really have to hide from Benedict is how they're really getting the diamonds. Bobby does bring a man & a woman with him but it seems to me that they're not real agents and there to sell himself as being there on official business. He picked them up in a diner and didn't bring them from the office. Another problem with using real FBI agent Bobby is that both Banks and Sponder encountered him. Maybe they'd assume he was a just a con man and not blow his cover.
