Plot hole: The scene in Central Park where Bud tapes Gekko never would have happened. Gekko's comments imply that he was unaware of Bud's arrest earlier that morning (not just that Gekko was unaware he was being taped). (1) Gekko makes comments that the Feds are pleased with, at least to some extent incriminating himself. (2) Gekko doesn't say something like: "OK, now you've been pinched, here's what you do." BUT - how in the world would Gekko not know of Bud's arrest? Even in the days before the internet, information spread like wildfire on Wall Street. All the brokers in Bud's office would be on the phones saying "they just arrested Gekko's broker!" Everyone on Wall Street, especially someone like Gekko, would find out, and far more quickly than the time it took to schlep Bud up to Central Park and strap a recorder on him.
