A criminal is an odd thing. First he’s usually supremely thick. Criminals, you see, think everyone is more stupid than they are. They cannot carry out their crimes if they thought that everyone is ahead of them, wise to their every move. But they just keep getting caught!
The guards are wise to how stupid most prisoners are but it is always fun to see it carried out in the flesh so to speak. Criminals think if they act like being in jail is very hurtful they will be treated with kid gloves. “I’m innocent and in the wrong place, etc, etc.” is their thinking. These officers aren’t having any of it.
