Early on Gibbs and Fornell are sitting in Fornell's parked car, a car with headlights on moves round them. The lit headlights are visible behind the parked car, through the rear window. Next shot should show the other car passing as the parked car is next to the curb and Fornell is behind the driver's wheel, and Fornell is the next shot, looking out on to the street.
Near the end of the episode, Gibbs and Fornell pull up on either side of the crim at a servo and both aim a gun at him. As they are facing each other they could shoot each other as well as the crim. A bit of a tactical error.
Gibbs calls the victim "Private Ron Flegman" (at around 7 minutes). All other references (by Tim, Ducky, Tony, and Gibbs himself) throughout the episode call him "Corporal Ron Flegman".
