How do journalists accurately cover news without being neutral?

Our book states that journalists should practice objectivity but not neutrality, so that brings up the question: How?

"Journalists must maintain an independence from those they cover," as said in The Elements of Journalism (Kovach & Rosenstiel). This means that they cannot let their emotions play a role in their reporting.  They must remain detached from the specimen of their story.  If they let their emotions take over, then they become biased and produce their story from a certain side.  Journalists must be committed to truthfulness. They must be independent from class or economic status.  They must also be independent from race, ethnicity, religion, and gender. 

Elements of Journalism shows William Saphire's views on the role of loyalty in journalistic verification.  Saphire says loyalty in journalism lies within a combination of friends and colleagues, political ideology, and truth.  Journalists should not let any of these sway their story in any certain direction.  The story should rely on facts, not information clouded by judgement.  

Knowing this, my perspective on the news has changed.  I was not aware of the impact that objectivity has on journalists.  I have a harder time believing what I'm reading contains both sides to a story without influence of emotions.
