That is not a fun fact at all. This punk should be locked up in a prison, not taking it easy in a halfway house for 311 days. You have diminished my enjoyment of this story. But thank you :) for adding to my understanding of federal law.
The 311 days will be in a federal prison, not a halfway house, though it certainly won't be a maximum security prison.
Back in the day when I did white collar criminal defense (I do civil litigation these days), I had a few clients who served some time in halfway houses and they hated them-- they are always full of junkies.
