Not sure why it would come as much of a surprise that a person who almost successfully conned his way into a prestigious clerkship and then entirely successfully got himself admitted to Stanford Business School despite an expulsion from Harvard would have a complete understanding of basic securities laws, but here you go:
Mathew Martoma attended hedge fund SAC Capital Advisors LP's annual compliance training sessions two years in a row, an officer with the firm said, testimony that could bolster the insider-trading case against the former portfolio manager. The testimony by John Casey, an SAC compliance officer, could buttress the government's contention that Mr. Martoma knew that what he was doing was illegal when he allegedly obtained inside information from two doctors involved in an experimental Alzheimer's drug trial...Mr. Casey said he went over the firm's code of ethics and insider-trading regulations with attendees during the sessions. Mr. Martoma's name and signature appeared on the sign-in sheet for the ones held in 2007 and 2008, indicating that he attended both, Mr. Casey testified.
So far it seems as though Martoma and his representation have been arguing that he did not commit insider trading, period, rather than he was but a simple man who didn't know what he was doing was insider trading, but it would be mildly-moderately amusing if they suddenly shifted gears to claim the latter. (And if they want to go in that direction, a jury might not exactly be flabbergasted by a revelation that, say for argument's sake, he doctored his records from Compliance College and never actually attended those sessions!)
