Other mistake: Following the accusation against the sheriff, the confrontation between the Mayor and Jessica is marred by a visible technical glitch. A negative-style overlay runs through the scene, including a light flare above the Mayor's head, a thick black line across the frame, and a whiteboard intermittently superimposed over the image.
