It's more of a slap in the face of the fans. As we tell those in the music industry who dabble in politics, "shut up and sing". The fans paid to watch him play, not recline on the sidelines.
What? He wasn't lying on the table during play, he was reclining while the jawing and fighting died down.
Please, hold him responsible for running into the stands at first, but don't start making stuff up.
How was he gonna play when the brawl was going on? And Artest was trying to stay out of fighting, until the fan threw the cup at him.
