When Agent Lisbon prepares to leave the ditch containing the body of Melanie O'Keefe, the camera is filming her from her front as she begins to remove her gloves. The next shot is filmed from behind Lisbon (and outside of the ditch) as she climbs out of the ditch, but in this shot both of her gloves are still on her hands.
