Consider that the actual police were there at all. They probably didn't each go on their own initiative. Apple's guy called an SFPD guy, who arranged for the officers to go along. So someone in the SFPD hierarchy was in on it.
No one in the SFPD is going to testify, or state during an investigation, that the Apple corporate police said anything that would lead the victim to believe that Apple's people were real police. Even though that was the whole point of the officers to be along, so the words "San Francisco Police" could be spoken, with all implications that come along with that.
