I think it is less about pictures being taken but a guy given a badge and now he is high on [perceived] power. Most of the time one can deal with them by a friendly request for clarification on which grounds they want one to do something. For the remaining few, if one has the time: Just let them call the cops. I myself have handed out badges and walkie talkies to untrained "security" folks at events and my estimate is that I had to pull about 10% out during their shift due to abuse of power and tell about 80% to not come back after their shift. From a security perspective, the 5% or so we had as regulars on staff were the only ones you'd rely on; that were also the folks who spend most of their shift just sitting around, but when there are real problems they deal with them level headed but efficiently. If it helps the OP: The guy's superior is probably just as annoyed as you are by his guard's behavior but he does not have the luxury to simply replace him due to crappy pay and therefore a lack of applicants.
