I've several times written about how the News Media handles political stories and crime stories.

Today, the police arrested a woman who was in the Captain America movie because they alleged that she had committed second degree murder.

This gives me a chance to demonstrate what I am referencing but I'm not going to read all the articles just look at a few of the headlines.

Most of the headlines I've seen are reasonably unbiased, others not so much.

Right way to write a headline (There are other examples but I'm short on time.)

TMZ

SFGate

Fox News

NY Daily News

Falls short of good but isn't horrible

The Daily Beast (Uses "allegedly" which is a prejudicial word. It is correct to say "The Police allege that she killed." It is bad to say "She killed allegedly." An adverb modifies a verb and tells how something was done. It implies that she did indeed kill in a manner described by the adverb,)

Bad

KCTV Kansas City wrote a headline that tries to fix itself by adding "police say" as the last two words.

Horribly wrong

Metro Puts quote marks around a prejudicial statement. I'm not doubting someone may have said that but whoever said it was speaking prejudicially. Putting quote marks doesn't change the fact that this news outlet used a biased quote for its headline unlike many others news outlets.
