Chain Jail is a term used to describe a type of prison system where inmates are physically restrained using chains. This method was historically employed to prevent escape and maintain order among prisoners. The use of chains can vary, with some inmates being shackled to a fixed point or to each other. In modern contexts, Chain Jail is often criticized for its inhumane treatment of prisoners. Many human rights organizations advocate against the use of chains, arguing that they can lead to physical and psychological harm. Alternatives focusing on rehabilitation and humane treatment are increasingly being promoted in correctional systems worldwide.
