Considering that Mrs Campbell's reaction to seeing Sydney Crosby was to immediately call in the newspapers and/or make him have a conversation with her daughter, I would think that the policy has been justified by this sequence of events.
I mean, Jesus, it's not like the DMV has a bunch of guys in the back room just waiting in case there's a need for crowd control. And even if they did, a crowd-control side show is going to delay people from doing whatever it is they're trying to do more than getting the "distraction" out of there as soon as possible.
and seriously, even without the policy this is a non-issue. If I walk into the DMV and they let me skip line, I'm going to skip the line
