If you had to go before a discplinary board, would you want a fellow inmate to be on it? (the board)
You get two people to pick as your defense witnesses. When i did it, i only took the Corrections Officer who was my direct supervisor at my job (landscaping). He came in and basically gave a character reference on my behalf and the DHS liked his testimony enough to release me from the SHU into gen pop right away. I would not have an inmate come to represent me, the staff believes their own kind more than another inmate who could easily alter the story.
