Question about Google Earth....

Are there "people" who work for Google that their only job is to scan over the world 24/7 searching for anomalies and blacking out those anomalies?
Like say after the google car sends in its pictures to the mainframe and just happens to spot an alien, a ufo, a murder in progress, etc., or something WE aren't supposed to see, do they have people that intentionally swipe this from our view?

Thanks in advance.
