Casino Deleted YouTube Gambling Videos? :/

I saw a video of a Woman filmed losing her money on a slot and she was PISSED and giving the Camera death glares. Comments said something like,"Oh my God, you filmed her losing her money? She should have reported you to Casino Staff. I would have reported you to Casino Staff if you filmed me losing my money. "The Uploader said something like,"She DIDN'T see me filming her! I filmed her discreetly, LMAO!" How do you explain the death glares right at the camera then?

That video was deleted the very next time I looked it up. The Woman must have reported the video to YouTube Admins or something, or to the Casino Staff themselves probably saying something like,"I didn't give him permission to film me losing my money. Please delete this video."
