The SHU or Special Housing Unit is the area of segregation that has no time limit. Prison rules are set by and followed only by prison personnel and no other outside forces may weigh in. Inmates are not entitled to attorney representation or other rights afforded by regular citizens. When the BOP states "they are investigating", there nothing an inmate can do. They have to deal with the rigors of the SHU. Our advice is to send him a lot of mail, magazines and books because he is on 24-hour lock-down. He gets two one-hour recreation sessions in a small outdoor cage that allows sunlight. He is allowed only three showers per week, only one 15-minute phone call per week and a sparse list of commissary items. Make no mistake, this is punishment on top of punishment.
