Bear in mind that this was a Fed trial, and he's going to a Fed prison, and he'll serve the full nine years, there being no parole in the Fed system. It may seem a little light in duration, but this guy's life as he knew it is over. He'll never again manage a business and take home bazoogles of money in salary, perks, bonuses, etc. At his age, he'll likely never have a productive job again.
There will be appeals, of course. And immense public outrage if they work.
Yet, despite all of this, it doesn't seem any of these kinds of cases communicate anything to other white-collar miscreants, any more than have the various financial scandal cases of recent years. We all know there are others out there right now pursuing various schemes to embezzle, steal and/or cut dangerous corners with their products and services. They just think, like this guy did, that they can get away with it because they are smarter. Some will. Some won't.
