In general, despite the concept of equal protection, prison officials have wide discretion to manage prison life. In part, that means that they don’t have to treat all inmates similarly. For example, many prisons classify inmates as maximum, medium, or minimum security risks, and treat them accordingly. (However, laws and procedures may vary at least somewhat from federal to state prison, and from state to state.)
Minimum-security-risk prisoners are usually housed in a section of a prison with fewer restrictions on movement and greater work opportunities. Factors that prison officials may consider when assessing a prisoner’s security classification include:
Prisoners who are unhappy with their confinement status may seek review, especially if they can show proof of specific factors that warrant a lower risk classification, such as work skills or medical needs. But it’s most effective to present such documentation when a prisoner is first confined. Prison officials will be less inclined to change their minds once they make a designation, and courts often refuse to second-guess officials on a process they view as prison management.
