“Why” is not part of journalism. Who, what, when,where, how. Objective. Example: Colonel Mustard (who) whacked (what) Mrs. Mustard ove(who) over the head (what) with a chair leg (what) yesterday evening (when) in their den (where)causing her to die (what). The How is implied, but the why cannot be objectively known. Maybe she was cheating on him, maybe she caught him cheating. If you want the why, present the facts and let the reader decide.
You mean “President Obama, why do you have the SSN of a dead man issued from a state you never lived in?” is not a question a journalist should ask in an article on that very subject?
Sorry. Why is very much a part. That is why it’s called “The 5W’s of Journalism”.
