This is...intriguing. A McCain poll worker volunteer claims she was mugged by a tall black man, who after seeing a McCain bumper sticker on her car became enraged, beat her, sexually assaulted her, and carved the letter 'B' (ostensibly for 'Barack') on her right cheek.
Which is where the intrigue begins:
I guess that's actually B for Backwards.
UPDATE: And, as has been confirmed (not that we needed it), F for Fake.
UPDATE II: I've removed the original picture of the woman's entire face, since it's become clear to me from the footage I've seen that she is very troubled. The point here isn't to criticize or embarrass her but to chastise those who so readily hyped a story that was fake literally on its face.
