Continuity mistake: While Tricia Skilken is competing in the Beam finals, Wei Wei's position on the bench changes. While the shot is on Haley, Joanne and Wei Wei, they are sitting in that order (from left to right). When the camera's focus shifts to Tricia on the beam, Wei Wei is sitting on the left (you can tell by the leotard colors).
Character mistake: At the very beginning, when Haley is in court, the cop says that the property damage from the previous scene looks to be about $14,000. Although we can't expect a cop to know the true cost of the property, the only things damaged were the large window and maybe the metal framework supporting it. The window couldn't be any more than $1000.
