So this whole Libor rigging thing has come as a surprise.

Remember Matthew Kluger? To recap, he's the mergers and acquisitions lawyer who spent two decades feeding inside information to convicted insider trader Garrett Bauer, that he picked up from partners at the six different law firms he worked at over the years. The operation, which included Kenneth Robinson, an old friend of Kluger who acted as the tips mule between MK and GB, went very smoothly for a very long time (17 years), and would have continued going smoothly had Robinson stuck with the plan instead of deciding to start making the same trades as Bauer, raising suspicion with SEC, which was watching the men and used "relationship analysis" to determine they were "part of the same trading scheme and had a common source: Kluger." In March 2011, federal agents showed up to Robinson's house and after thinking it over for a couple days, he decided to cooperate by giving prosecutors a step-by-step guide to how the scam operated, telling them Kluger's name, and recording conversations with Kluger and Bauer in which the two said things like "I went right up to my apartment and I broke the phone in half and went to McDonald's and put it in two different garbage cans" and "I can't sleep. I can't sleep. I'm waiting for the FBI to ride into my apartment" and "We have to get all the fingerprints off that money. Like you wearing gloves or something and wiping every bill down or something" and "There is no way [these cell phone conversations] could ever be recorded." Robinson was ultimately sentenced to 27 months in prison, Bauer got nine years (despite his 147 speeches about how insider trading is a bad idea on the college lecture), and Kluger was handed 12 years, beating Raj Rajaratnam for "the longest insider trading U.S. history." Recently, Kluger sat down with Bloomberg to offer a few more specifics re: how the scheme went down ("Sometimes it was a deal I was working on, sometimes it was a deal I heard being discussed in the office"; "I would call Ken and say 'X/Y/Z company is considering a takeover of Q company") but what he really wants to talk about? What was the biggest surprise and hardest punch to the gut in all of this? Is what it was like finding out that his buddies were stiffing him on cuts of their ill-gotten gains. "On the day I was arrested, when they showed me the criminal complaint against me, finally that day, I saw the amounts that had been traded and I was absolutely shocked. Our agreement from the beginning was always that that profits were being shared equally three ways. I felt very used and manipulated, that he was basically pumping me for information, that he was then lying to me about how he was using and then allowing his obviously better friend to make millions and millions of dollars while telling me that that was not happening. “Maybe you want to laugh and say of course there’s no honor among thieves,” Kluger added. “But even when you’re doing something you’re not supposed to do, I trusted that they were honoring the commitments that they had made.” You can imagine Kluge's utter dismay to find out that such was not the case. It's one thing to get nailed for insider trading, it's another to find out you could've been making 10 times the profits while doing so.

Remember David Slaine? For those who need a refresher, he is the former Morgan Stanley managing director and ex-Galleon trader who began working as an FBI informant in 2007 and who was outed for doing so by the Wall Street Journal in January 2010. At the time, we learned a few notable things about Slaine, some of them germane to his role in helping the government go after people trading on material non-public information, others special in their own way, like: 1. He takes french fries, and perhaps all snacks, very seriously. In 1993, Slaine triggered a fist-fight with a colleague on the trading floor after needling him because he wouldn’t share his french fries. Others broke up the fight. 2. He doesn't wait for people to towel off and get dressed before knocking their teeth out. One morning early in 2001, before trading began, Gary Rosenbach, then was the No. 2 executive under Mr. Rajaratnam, and Slaine were in a steam room together after exercising at an Equinox Fitness Club. Mr. Rosenbach was pressuring Mr. Slaine to improve his performance. As Mr. Rosenbach lay on his back on a bench, Mr. Slaine punched him, giving him a black eye and ending their friendship. 3. Humans aren't the only ones often asked "you want a piece of me?" He once smashed a computer keyboard in a fit of rage, says a person familiar with the incident. 4. While working on Wall Street, he eschewed the traditional channels of employee recruitment (Wharton, etc), preferring instead to pick up fresh analysts at the club. While at Morgan Stanley, he met [Craig] Drimal, then a nightclub bouncer at the Vertical Club in Manhattan. The two quickly formed a friendship based on a shared passion for weight lifting and their mutual ability to bench-press 400 pounds...Shortly after arriving at Galleon, Mr. Slaine persuaded Galleon officials to give a position to Mr. Drimal, who then was working as a bouncer at the Roxy nightclub in Manhattan. 5. Being a person with whom he "formed a friendship based on a shared passion for weight lifting and [a] mutual ability to bench-press 400 pounds," possibly the greatest line written about anyone who's ever worked on Wall Street and which which cannot be said enough, means little in the long run if he knows you've been playing it fast and loose with securites laws. In July 2007, the FBI showed up at Mr. Slaine's door on W. 57th Street in Manhattan and confronted him. Mr. Slaine agreed to help the government. At the time, federal prosecutors in Manhattan were trying to make headway on another investigation that eventually led to the charges involving Galleon. They asked Mr. Slaine who he knew that might be participating in insider trading. Mr. Slaine's answer: his friend Mr. Drimal, according to people familiar with the matter. In September 2007, Mr. Slaine—identified in the complaint as CS-1—tried out his body wire for the first time, meeting Mr. Drimal in New York. During the meeting, Mr. Drimal gave Mr. Slaine a piece of paper with four stock symbols, according to the complaint. He told Mr. Slaine the four companies were all acquisition targets. At the meeting's end, Mr. Drimal told Mr. Slaine to destroy the list. He warned him to "be careful" in trading the securities because no news of the takeovers had surfaced publicly...After the meeting, Mr. Slaine went to a nearby hotel where an FBI agent was waiting, says a person familiar with the matter. The pair went to a room where Mr. Slaine removed the wire. Anyway, Bloomberg recently checked in to see what Slaine's been up to these last couple years and other than his "multi-year experience" with the FBI being "tremendously traumatic," he seems to be doing pretty well.
