This is an excellent point. Anyone who has been locked up knows to quickly self-censor themselves, lest they become a target of the jailers. Lots of modern facilities suffer from this since they read all the outgoing mail and listen to the calls. edit: sometimes though, if you're willing to face the consequences, it allows you to write things about your jailers knowing that they are forced to read it. I remember a US federal 1st Amend. case where the prisoner had written that the mailroom lady was fond of sex with her cat. Said maillady refused to deliver the mail and it became a protracted law suit and therefore brought much more attention to the maillady's alleged proclivities.
