About whether or not the Federal prisons are the "luxury resorts" of the prison system, it seems to me that the true punishment of incarceration is the loss of freedom. No matter how "luxurious," is that really an option that any of us would ever choose for ourself?
I think if he truly is dying, he could probably be released to a hospice, without any risk of fleeing to some tropical country to live out the rest of his life in luxury. He has already been punished, and his name will forever live in the annals of infamy, remembered with disgust and dishonor. Isn't that the real punishment? What difference if his hospital room is a little nicer, or not?
