Although there is some risk of confusing the jury when presenting them with code snippets, prosecutors had Wang step through what the code is doing in a way that seemed pretty clear to me.
It probably helped that FTX’s engineers wrote decently clean code, with descriptive variable names and concise functions, and chose a very human-readable language (Python).
Note to self: if you’re going to write code to do fraud, make it messy and unreadable to reduce the chances it’s later put in front of a jury as evidence.
