Arresting the girl seems a bit much. Go give her a warning or something. Clearly it is a joke – does anyone really think there is a female Utah fan so passionate as to detonate a nuclear reactor if the football team loses to SDSU?
I mean, if it was the Rose Bowl, maybe, but non-conference to SDSU? Seems like some authorities are on a power trip.
In solidarity, all fans at the next home game should, in unison, repeat whatever words she used that caused her arrest. Force them to either arrest and prosecute everyone or drop the charges against her.
