Deliberate mistake: When Phoebe is about to destroy the lion statue, police cars arrive at the scene. Barely a second and a half later, suddenly the place is filled with cops who have managed to park the cars, step out, take positions, and aim. It speeds up the action of the film, but it's very awkward.
