Google does have an army of thousands who do editorial review. Their job, as I understand it, is to review the SERP as a whole, and to do that they check into each ranking site. It was laid out in general terms in this 2006 patent [webmasterworld.com].
This would be for relatively competitive searches, and it is for a review of the quality of the entire SERP. But if one of these editorial staffers spots something that's off according to their training, you know it will escalate up the chain of command.
That's a lot of words to say, "yes" ;)
