It seems you don't quite understand how our justice system actually works. We don't just put people in jail because we feel that they "did something wrong." We have to prove that their conduct violated specific statutes. The courts found that in Alyenikov's case, it did not. Not only that: even as alleged, it did not violate the statutes under which he was accused.
Also, please follow up with the others who are correcting you. You seem to be confusing the facts.

That's why its best if you use links for references in your claims. It's really starting to sound like some guy committed white-collar crime and got off on a technicality.
No, I'm just pointing out to you that the courts found that he did not commit a crime, and that the FBI acted too aggressively. What you do with that information is up to you. We certainly don't have to be on the same page about it.
But hey, if you're an honest person, maybe you'll be a good fit.
By the way, I'm not arguing for/against what happened to him once he crossed the line. I'm merely pointing out that he did knowingly cross a legal line, which as we know can get quite messy.
