History is full of people who went to prison or were burned at the stake for proclaiming their ideas. Society has always defended itself.
In jail a man has no personality. He is a minor disposal problem and a few entries on reports. Nobody cares who loves or hates him, what he looks like, what he did with his life. Nobody reacts to him unless he gives trouble. Nobody abuses him. All that is asked of him is that he go quietly to the right cell and remain quiet when he gets there. There is nothing to fight against, nothing to be mad at. The jailers are quiet men without animosity or sadism.
Every crime has, in the moment of its perpetration, Its own avenging angel--dark misgiving, An ominous sinking at the inmost heart.
The thoughts of a prisoner - they're not free either. They keep returning to the same things.
Prisons don't rehabilitate, they don't punish, they don't protect, so what the hell do they do?
