Reporters who go/went to journalism school are taught to "just give the unbiased facts" when reporting straight news.
For example, if someone crashed their car when it was raining outside, you can't say, "joe blow crashed his car because it was raining" because you're not the cop or an expert - you don't know for sure, and if sued, you'd have to PROVE the road was the fault of the crash. However you can say, "Joe Blow crashed while traveling on slippery Interstate 123."
When it comes to magazines/online, you're suppose to "paint a picture" of the situation because it's "second day news", and allows a certain leeway to bring the story to life.
That said, some "straight news" media impressions are intentional, some are not. Patriotism is measured in the mind of the individual viewing the newscast.
Bloggers are stating their opinions, so their reports are like letters to the editor with facts to make their point. Larger media outlets with journalists on staff should stick to the facts IMO...
