Artest came out of the stand and when he saw the fan, took an immediate "fight" position and then coldcocked him; the second fan on the floor came to the defense of the guy Artest hit, then some guy in a brownish suit hit THAT guy before O'Neal came flying from nowhere and hit the second guy again!
Lots of conflicting stories. I thought the guy in the suit jumped the one who slipped after fighting with Artest. The second guy was standing there but looked to be trying to defend his buddy when O'Neil suckered him.
