Like most American prisons, FCI Dublin also contains a SHU (Security Housing Unit), where any prisoners who are deemed to have broken prison rules are kept in segregation under a highly restrictive regime. Prisoners in the SHU spend more time locked in their cell than the general prison population, are only allowed out for limited amounts of time and must be transported to and from their cell wearing handcuffs. Depending on the circumstances, an inmate may spend weeks or even months in the SHU.
