You were the potential defendant, and you were facing indictment and prosecution for a crime 95% of jurors wouldn't understand, and your lawyer probably suggested that you accept the proffer. I can see how that might be a good idea, because a proffer is a gateway to the prosecution offering immunity, a good plea deal, or dropping the case entirely. Talking to the police/feds/prosecution under other circumstances, or accepting a proffer when you're not under investigation or without advice of counsel, is where the problem lies.
