The Federal Bureau of Prisons' Miami Correctional Center is such a facility. Prisons are designed to hold individuals convicted of crimes. Most prison facilities are exclusively either maximum, medium, or minimum custody facilities. Rarely are inmates with different classification levels mixed in the same facility. Inmates assigned to such facilities are usually reaching the end of their sentences.
Prisons are much different than jails.
The constant turnover of inmates in a jail doesn't happen in a prison. Prisons offer programs designed to rehabilitate inmates.
