This arrest was absolutely absurd. I voted other on this poll because I believe the most that should've happened was her being escorted out of the venue. Let me get this right...we're arresting people for expressing joy? She was arrested for excessive joy that was interpreted as disorderly conduct.
This woman did not deserve to be arrested at all, or even fined. She should've been sent out the door and that is it. You don't arrest someone for this kind of action.
