Freedom to Sue

Suing one for defamation charges seems all fair and square. But repeating the same charge on different people, on some cases, regular individuals who might just be expressing their opinions... 

What happened to our Freedom of Speech? The Right to Express? Democracy???

How far does this freedom extent to? Where does it start and end? The fact that freedom has to start and end at some point is pathetic enough. 

An UK Author was charged for his book on Capital Punishment in Singapore and the feedback he is now experiencing, is in the form of a prison sentence and a massive fine.

Are we acknowledging his claim then?
