Depends on what you are willing to accept as evidence.
If the single blog post on Jan 30 is all the evidence you need then you have all the information there is available at this time and it happened.
If hotel maintenance and management, Blast Structures International, are also considerations of what you would accept as evidence then there is no information that this ever happened.
I will gladly go through Real Raw News stories with you and do a comparative accuracy analysis. I will also go over Jeffrey Prather's history and why I don't get on board with everything he says.
Based off of the track record of Real Raw News, the details of the blog post, like the "ballistics guy" which is not a thing in this type of situation, a sniper shooting from a helicopter "200 yards or more" and that nobody can by tele-lens find a damaged window, my guess is this was completely made up.
Most likely they used this article to assemble the scenario as it contains all the key points on that type of shot:
https://www.wearethemighty.com/mighty-trending/americas-top-snipers-fire-heli... Not sure what decade the SS team at Mar-A-Lago come from but if they went around interviewing about a helicopter given the modern tech available these days I would say they need to be retired or re-trained.
Obviously this inside source doesn't care that Trump wants to "keep it in the family", an oddity for Trump in my opinion as I would think he'd want to broadcast this like crazy. Lucky for Real Raw News they got this information since it aligns perfectly with their user base and financial model for gaining profit through click-traffic and sharing of their posts.
Bottom line is anytime anyone tells me they have an "inside source" that nobody can have access to, even anonymously, and then they say it's not being reported to police, and the details are all things that can easily be looked up, I am suspicious. I think anyone could spend 15 minutes on google and write this story.
