Continuity mistake: At the beginning of the episode, the bikers are approaching the crime scene to be, and you can see the sun low in the sky in the shot, casting long shadows to the right of the bikes. When they are a little closer to where the shooting will take place, suddenly it is high noon; for there are no shadows except directly underneath the motorcycles.
Continuity mistake: At the end of the broadcast as Jake and Horatio converse in front of the police station. In the closer shots, they and the motorbike are the left of the entrance steps with a car parked on the right, then in the zoom-out shots they are on the right of those steps with a cop car parked on the left.
Continuity mistake: Throughout the second half of the broadcast, Calleigh's hair switches back and forth repeatedly between a very straight part toward her left side, and a part that curves toward the center of her forehead. It looks like she changes her hair comb every time she dons her lab jacket.
