Can and can not..

Media use words to attract us consumers, false or truth will not be recognized if they're good at playing words. But beside the question can media be sued for falsifying serious information?

here's a branch question for you :
1. What kind of false and truth are you talking about as all truth is a subjective truth and as long as someone able to play victim ,play the words, have a good lawyer with sweet mouth?
2. How can an information be considered as serious or not so serious/ important?

For example you saw a clickbaiting news and it seems like the writter/ media side on the killer. This media is 1 out of 20 who defend the killer and wrote about a case from the killer's side.
 
Let's say in this case- the reality is, what happened is- the killer is on news is not the actual killer. he became the killer because he's a good victim to be blame on. he's poor, he's on the wrong place at a wrong time, and he have nobody to defend.

Who justified the truth and false? Us who see, but from us who see- what kind of benchmark do we use?
