The guards have a watch commander who is supposed to make the judgement call. The watch commander was given instructions on who was and wasn't supposed to be there, most likely from Salesforce's on head of security, which he relayed to the guards. I imagine Salesforce created a standing order to have any removed that didn't have the correct badge. This was passed on to the watch commander and, unless Salesforce intervened, if asked for clarification by the guards the watch commander would re-iterate the standing order.
