I know that blurring of non-humans is commonplace, but this one kind of makes a subconscious political statement.

A graffiti artist has painted Uncle Sam flashing his ID card and (presumably) demanding to see your papers:
flickr.com/photos/jeffschuler/ ...

And Google Street View obligingly preserves Uncle Sam's privacy by blurring out his face:
maps.google.com/maps?f=q&h ...

Amusing!

Kewl; It seems that Google's face recognition technology really worked well. I'm not sure but we have this technology on Picasaweb and Google Image search. Right?
