About FMC Carswell

Behavioral Units = Cruel and Unusual Punishment

Marius is incarcerated in the high security Administration Unit at the Federal Medical Center Carswell in Fort Worth, Texas. According to the prison’s own literature, the unit is “designed for female inmates with histories of escapes, chronic behavior problems, repeated incidents of assaultive or predatory behavior, or other special management concerns.” Marius has never violated any prison rules. Clearly, he is being held in this unit because of his political beliefs and in an effort to silence him.
