I don't think they can until the FBI tells them it's ok to investigate and gives them the info. The booing and taunting of Boyle was clearly connected to his earlier comment the fans were holding up signs directly related to it. I have no problem with fans doing it, that's what fans do. I'm actually surprised fans on the road aren't chanting FBI everytime Arizona or USC play there. But for an announcer like Jacobsen, an ex player, to essentially apologize for what Boyle said it right up there with Carmelo's infamous appearance in that "don't snitch" video a few years ago. Boyle was asked a direct question and responded honestly, he didn't go after Miller unsolicited, he didn't even really mention Miller beyond saying he respected him. Jacobsen acted like he'd gone out of his way to insult Miller and that it was not classy. I can understand fans of those teams not liking it but an announcer and ex player acting like what he said was somehow wrong I just didn't get. I would have got it had it been Muehlbach but Casey as near as I can tell has no Arizona ties.
