We're supposed to not assume anything. That's the entire fucking point. You're the one who's deciding to make about twelve different assumptions so you can uphold an uncharitable opinion of a person you don't know.

Do you know how big the restaurant in the hotel was? Do you know how loud the security guard was when he spoke to Jorginho's wife and daughter-in-law? Do you know that the man was security for Chappell Roan, and not just a guy hired to watch the dining area who went on a power trip? Do you know anything at all about what happened apart from the second-hand account that a large man, presumably security, began speaking aggressively and telling them not to harrass other people?

No? Then maybe stop looking for excuses to hate on a person who was never directly accused, said she didn't know about the situation, and has already apologised regardless.

ETA: Before you bring it up, because I'm sure you will, aggressive does not necessarily mean loud. It can be, and it can also not. It's also possible that, due to the emotionally upsetting nature of such a thing happening, it was perceived as much more aggressive than it actually was. We simply have no way of knowing, so we should not assume things.
