Before accusing someone of
Before accusing someone of "ravings" or blaming an editor, you really should educate yourself by understanding that prose has progressed beyond simple grade school grammar. I would recommend that you read "Building Great Sentences: How to write the kinds of sentences you love to read" by Brooks Landon who explains that not all writing needs to be---or should be--- short monosyllabic noun, verb, direct object construction. I admit the sentence you point out is not perfect---missing an "s" in the word "case" and it could use a "that" removal to make it tighter, but it is otherwise a good sentence that supports the lead sentence of the paragraph. Yes, I am a professional writer. But even professional writers have typos and auto-correct errors when having to write fast and accurately. Try typing a page on someone else's keyboard before launching into your own "ravings."
