The news is something that a journalist makes. There has to be a sort of tension when reading a piece of news, because if it wasn't for tension, that I, not the news.

Explanation:

The journalist has a mission to find out the truth and to says it but the other thing is that he has to keep the power of telling the news.

If everything told is already known, when reading it it wouldn't be news. If you say to the public that bad things are happening, but there are solutions for this, that is not news. The journalist has to decide what will be represented as news.
