Want to understand how pervasive media bias works? Read on.

Check out this awful headline from @AP. A gun was found on the scene, there are bullet casings and bullet holes on nearby walls.

This isn't simply an allegation. This was clearly was a gunman.

It would be bad enough if the Associated Press alone published this headline. But because @AP is a wire service, many other leading news outlets have republished this content, often verbatim.

Here's the article on the @WashingtonPost, for example.

And here's the same article, and same headline, on @YahooNews.

The article was republished in plenty more well-known media outlets. Here it is on the @ABC website.

Moving forward, the content of the article is deeply problematic. This is how an article about an attempted shooting attack begins: by focusing on the *response* of the security forces to being attacked.
