A man was dismissed for putting up a Dilbert strip - read the article here: http://www.desmoinesregister.com/apps/pbcs.dll/article?AID=/20071219/NEWS/712190360
In which system would people be fired for drawing cartoons of their "leaders"? You guessed it: a dictatorship system. In fact, the subordinate didn't even draw a cartoon - he simply put up a Dilbert cartoon. For that, he lost his job.
Guess how bosses identified the 'culprit'? They viewed surveillance tapes. Which obviously pre-supposes the existence of surveillance cameras. What does that remind you of? You guessed it again: a dictatorship system.
The issue went to court, and the employer lost.
