The security was an off duty police officer from what I understand. I don’t think that charge will hold up, if an officer is off duty is it still assault on a police officer? Maybe a freeper who knows will answer that question.
Unless it happened outside the room. I didn’t see an assault. It will be interesting to see how the arrest holds up. I would say the worse they could come up with is trespassing, since he was asked to leave. The district is asking for more troubles than this is worth, pressing any charges.
