My guess based on the video, is that it was a snag, likely accidental. Any deliberate, or potential threat with the big security guys right there, would have gotten a very prompt response by ALL the security guards there. This happened once IIRC in West Palm beach. Tori Amos was doing a meet & greet, and someone tried grabbing her, and in the blink oI'dsf an eye, her guards were on this asshole like stink on shit. I would guess that her guards would have reacted in a guard like manner if there were an actual threat. The guards are good at what they do.
