You're ignoring the other charges he had, the prosecution offered him an AMAZING deal. You can't just not prosecute people because they're depressed.
Amazing deal? Really? Do you think that serving 6 months or more for his "crimes" is justice?

So, your "guess" is as good as mine, or any of my fellow armchair analysts on HN? Are you sure Aaron even considered you a friend?
Or perhaps, you were just trolling HN, eh?
