After Hooker shoots the guy and he falls down the steps, his head is near the steps and his gun to the right. In the following scene, his head is away from the steps and the gun to the left.
Hooker and Romano are both dressed in yellow T-shirts while outside talking to Stacy. Hookers T-shirt says Physical Training Instr. and Romanos says Asst. Physical Training Instr. Once they go inside and meet the model Romanos shirt no longer says Asst.
Romano and the model both use the term "biopsy" speaking about checking into a subject of the investigation. This is a medical term not used in police work.
