Re: Actual time served
For prison sentences under 10 years involving non-violent crimes, you can be sent to a "club fed" prison. There are no longer tennis courts, and I can't imagine anyone wanted to go there, but it is not the horror stories you hear of maximum security pens.
From the article:
As Kerik explains it—and I had to keep reminding myself that he was once a prominent authority figure in the system—"there are four or five classifications for the BOP [Bureau of Prisons]. You have super-maximum security, if there's a terrorist or a super-violent criminal. You have maximum security, which is the next level down. After max, you have medium." That's where Bernie Madoff is, by the way. "Then you have low. Then you have minimum." To be eligible for a minimum security "camp," your sentence has to be less than 10 years (or has gotten to under 10 years) and you need to be considered "nonviolent."
