Private citizens dont know the laws with LEO's or retired LEO's being allowed to carry, they only know the signs that are posted for no firearms for regular people. Best bet is to call the security office and ask, dont ask ticket sales or anyone that doesnt know better. But I can tell you that most of these events dont care if you're a LEO or not, they most probably wont allow it. Stupid in my opinion, because you'd be the first to help in an emergency, but not much we can do about it.
No firearms
I don't think you can, they check all bags and have metal detectors. They do have security and police, and depending on the acts they may increase police presence.
