Factual error: In one early scene (maybe third or fourth of the episode) Special Agent LaSalle greets and shakes hands with a sailor he knows, a U.S. Navy Chief Petty Officer. The CPO is wearing a gold surface warfare insignia, which is an Officer's device. A CPO should be wearing a silver insignia. Later in the episode the the same Chief Petty Office is shown close up, still wearing a gold pin, not a silver one.
Factual error: At beginning of the episode during the evening a marine gets hit by a taxi. Titles. Pride arrives to look at the scene with the M.E. present and it is during the middle of the day, going by the shadows of the onlookers. Sure they would not leave a dead marine lying in the street for that long?

Revealing mistake: In the forensics lab Carol Wilson is saying to others that the rat caught on the ship is healthy. In the ensuing conversation the respirators they are wearing are so ill fitting as to be pointless - Carol's mask does not even touch her nose.
