Ummm ... wasn't it O'Neal who came in throwing Haymakers? The tape shows Artest lunging at the one guy, then being pulled off and dragged out to midcourt after a number of other provocations. O'Neal, OTOH, is clearly out throwing haymakers left and right.
If you can't get the story straight, your outrage is a little selective.
It's true that O'Neal took a running punch at a guy on the court, and that seemed to be the worst blow thrown during the entire incident. I heard one expert say he'd be shocked if O'Neal is not charged with a crime.
But Artest not only pushed a guy, he also threw punches. Why do you think he went into the stands - to chat with the fans?
