So, what you're saying is that comma splices and other grammatical errors are okay in journalism even though they're frowned upon in all other forms of literature and even in business emails?
That would certainly explain why I've noticed grammatical errors on the front page of an estimated 99% of all the newspapers I've ever read.
I guess what I'm saying is that what some call "errors," others don't see anything wrong with at all, depending on the format.
Most novels would have "errors" throughout. Thoughts of the narrator, descriptions of scene, quotes of characters (to include use of dialect) all deviate from textbook English. It's also what makes those works interesting. And even within the boundaries of "textbook English," there are writers like C.S. Lewis, who committed the unpardonable sin of writing in second person in many of his books, but it helped draw the reader in.
Speaking specifically of newspapers, if that newspaper is using AP Stylebook, the newspaper is "right" and textbook English is "wrong" in any conflict -- when used in that specific format. And then you have the New York Times, which has its own stylebook (hence why the Times would quote Nick Saban as "Mr. Saban" whereas no other American newspaper uses "Mr.," "Mrs.," etc., when reporting quotes). My first newspaper didn't use AP Stylebook, but my second assignment (with a magazine company) did, and it took some time for me to break habits and adopt that style.
Our previews and wrap-ups are hybrid stories/op-ed pieces, which is how analysis tends to read. In order to make them interesting, we try to inject humor and be more conversational in our approach. Most seem to appreciate it.
That doesn't mean there are never grammatical errors; our staff is small and we're our own editors, proofreaders and uploaders. Mistakes will slip through. The uploader sometimes removes a line of text. But mostly, you read it as I hear it in my head. The three writers most influential to my style were Lewis Grizzard, C.S. Lewis and Max Shulman ("Rally 'Round the Flag, Boys"). What comes out is typically a mash-up of what I want to say, presented in a way they'd say it, as a group.
