Here's an example of why the semantics of many media headlines bother me. Take this example, from a reputable source: "British tank crushes learner driver's car in Germany"
This headline, coupled with the photo, almost certainly lead you to the conclusion that the tank driver was in error. Reading the article reveals that the student driver drove out in front of the tank, leaving the tank inadequate time to stop.
Sadly, headlines are often all people read these days, especially on social posts references news articles. Often, the headlines are non-specific or provide unnecessary leading information. I ask, is it essential that your headline read "Walmart shooting proves fatal" when "Shooting proves fatal" or "Perth shooting proves fatal" provide the reader with sufficient information, rather than leading them to connect the shooting to Walmart itself? If a person is convicted of child molestation, do we need to know the children's gender; or does that merely serve to bolster negative stereotypes if the victim is of the same gender?
It's important to extract only the most pertinent information for these headlines, captions, and the stories themselves. Without being mindful of such subtle and seemingly innocuous elements, the storytellers are inadvertently (I would assume) leading readers to develop skewed impressions of involved or related parties.
