So youre getting a lot of responses, but everyone is latching on to the word hanging instead of ligature.

These are different things. Ligature does not involve the weight of the body, but a constrictive device on the neck. 3 nooses, one on hands, feet, and neck, would make you fully mobile until the rope was pulled.

Suspicious, definately. Should this place exist? No. Insane to be happening in a prison, definately. Unheard of? No.

The confusing part is the use of hanging, as that is a very different form of strangulation.
