The narrative is entirely unchanged by the new footage and even that footage wasn't exclusive to the doc. It had been shared before. But also, and here's the important part, you can't expose a "truth" that everyone already knows. The "rehearsal" footage doesn't change the who, what, where, when or why. So what's it exposing?
This article isn't news and you know it. You're trying to defer to a reputation instead of actually justifying it by pointing out some hard hitting journalism in the article. And just for context, The Wall Street Journal is controlled by the world's sleaziest newsman, Rupert Murdoch. Corporations are fictional. They are run by people. And people are real. And Rupert Murdoch is a real piece of shit. Promoting his propaganda rags and tabloids is indefensible. Trying to clutch your pearls at someone criticism a Murdoch controlled publication just shows that you don't understand the supply for the information you're consuming. Also, I think you probably work in marketing but call yourself a writer.
