You mean like the St. Louis Cardinals?
Artest and Jackson should be gone for the year. You dont EVER go into the stands unless you actually see your family there and in danger or something. They didnt even know if they were pummelling the right guys.
If they were simply hitting fans who came onto the court, its a different matter. All bets are off when that happens.
If security/police find who threw beer/foreign objects and the fans that stormed the court, they should be ARRESTED.
Only in sports can people give other people and even fans beatdowns and consider a lengthy suspension harsh. If I assaulted someone at my job, I'd be fired AND arrested.
