I can appreciate your anxiety. The Federal government casts a wide net when they investigate, and if you're on the outer perimeter (casualty of circumstance, others far more closely involved) this is probably terrifying for you.
That said, I'm not going to be able to tell you anything different from what your lawyer has already said. The Federal government has a statute of limitations of 5 years on this sort of an offense, and they are not going to say who is and isn't off the hook until the whole investigation is complete. The more others who are or could likely be involved, the longer the investigation will take. So like it or not, you're really going to have to focus on the rest of your life -- hard as it may be -- or you'll be heading straight for an ulcer.
I told you in my last post, and I can reiterate this, that if they are giving you your computers
back, then this is as good a sign as you're likely to get. If they found anything in them that could hurt you, they would not be returning them.
I also think that you were very wise to retain a defense lawyer who had been a Federal prosecutor. He will not only be experienced, but he knows the way the prosecution works. I'm sure he knows what he is doing, and it's an advantage to have a defense lawyer who has familiarity with the perspective of opposition. No, he can't give you a guarantee, and neither can I, but if he's being reassuring, I'd go with that.
