Again, couldn't agree more that the fan was wrong. But Artest was wronger [sic] for going after him.
Maybe you're the type who would just sit there and take things being thrown at you --- maybe you'd have no choice but to cover your head with your arms and meekly take it or you'd run away and get laughed at for it --- but the beer throwing has been going on for a while now --- the fact that no one has addressed the issue of the unruly fans --- until Artest did --- is the problem. Why pay security at all if this kind of thing just goes on?
