Continuity mistake: The lone shark's thugs break down Mac's door trying to get to her husband, Chris Ragle, who is hiding in her apartment. Although the door is splintered to pieces, later that night, the same door is back in perfect condition, including the custom paint job that matches the interior decor of the apartment.
Factual error: At the beginning of the episode Rabb evades two heat seeking missiles while flying a Mig-29. When Sarah asks him how he did it, he explains that he got them between the missiles and the sun which made the missiles target the sun instead since "it is a bigger target." While the sun is indeed a far larger source of infrared radiation than a fighter jet, all anti air missiles since the 1950s come equipped with navigation systems in their nose that contain an optical filter. This filters out unwanted data, including the specific infrared radiation coming from the sun. Hence it is impossible for modern anti-air heat seeking missiles to target the sun.
Character mistake: When Harm is questioning agent Novack about whether there was an "angry demeanor" amongst the Marines on the day of the shooting, Mac objects that he is "leading the witness." However, Novack was her witness to begin with, and Harm was cross-examining her. Leading questions are permitted during cross-examination; as an experienced trial lawyer, Mac should know this.
