I get re-writing. News organizations have re-written copy since the dawn of journalism. I even get adding content and opinion to existing news stories (I don't like it much, but I get that's what many customers expect nowadays). But re-writing to, potentially, undermine the premise? That's troubling. The copy editors --- and that's what they are --- aren't in the newsroom that produced the story. They don't know what went into the news gathering process or editorial discussions. All they know is what they read. It seems to me that changing a headline (or the body) of a story to undermine the initial concept is just flat out wrong. It misleads the public --- maybe intentionally --- and takes another step towards disintegrating the public trust.
Maybe I'm just old fashioned.
