#[3] and I were present at both "pro forma" hearings, in November and February. We recorded an episode after the first hearing. Not much new information came out in the second hearing. Mainly that they just managed to get access to his laptop and that they believe he also operator a relayer (his lawyer denies this).

Without access to the full dossier it's hard to figure out what exactly went on. But even if all the details were clear, we might still end up with a very bad precedent. Either because the judge has no clue how the system works and will be satisfied with a handwavy reasoning: there was money laundering (A), there was profit (B), therefore A caused B. Even if all profits came from the appreciation of tokens due to degen traders, or just because he bought ETH early, and not a penny from the actual activity in Tornado Cash.
Or it turns out he did run relayer, in which case they'll move on to arrest anyone who makes money from a mixer.
