In the Federal prison system they have a punishment called "diesel therapy." If you buck the system they put you on a prison bus to another joint where you spend a few days in a holding cell with no access to a phone, your mail, any kind of rec. Before you can get released to the general population they put you on another bus to the next joint and the same routine. There are over 50 institutions in the BOP, so there are lots of places they can send you. Your mail and your belongings never catch up with you, and only rarely can you make a 10-minute phone call. My friend got in trouble for a book he was writing in there and spent 6 months on the bus like that until his lawyer got an injunction and they had to leave him in one place. He was allegedly ex-CIA, and after retirement got bored and participated in a bank robbery, as the pilot to fly the loot from NY to Bermuda. He sold the book to a publisher and received a $35,000 down-payment into his prison commissary account while he finished it. I borrowed his book from the public library a few years ago, an interesting and funny story about some prisoners who start a gambling business inside the walls ("The Get-backs of Mother Superior," by Dennis Lehman, 1987).
