Honestly I think some is fake and some is real but it is hard to figure these things out now days. Post like this are a great example. It’s a statement with no actually factual backing aside from a video we can’t understand that is attached. This video could be or have been a training video, training session, film set for a tv series or movie, it could be a high school film project or exactly what the implication in the post is but nothing here can confirm that for me at least.
