I feel like there is more to this story.  Apparently the officer was trying to protect himself because she was punching and kicking him to try to resist arrest.  That doesn't make it okay for him to punch her in the face, though, he should have been more professional.  But he is human and it might have been his first instinct, who knows.  I saw that she is suing the city for a million dollars, I bet she is trying to bank on this whole incident.  I don't know how I feel about this really.  I don't feel much sympathy for the woman.
