The New York Times has is currently featuring a story with the headline:
Blackwater Shooting Scene was Chaotic
If the point of the headline is to make me want to read the story, then this one gets an F. You can't take the one thing I probably already knew about incident and use that as bait to read the story.
Blackwater Shooting Scene was Serene would be headline worthy. Otherwise, the mood of the scene probably shouldn't be the feature.
